The ring setting (ringstellung) was NOT the startposition, but the relative position between the internal wiring of the rotor and the alphabet ring with its notch. More details about the rotors <a rel="nofollow" class="external text" href="http://users.telenet.be/d.rijmenants/en/enigmatech.htm">on this page</a> The 'start position' or initial start position you are refering to is the actual message key, that is at which letter the rotor was turned at the beginning of the message, and was different to each message. This rotorposition was set manually on the exterior of the machine (and changed the letter in the little window). Wehrmacht, Luftwaffe and Kriegsmarine changed the plugboard each day. The internal settings (rotor selection and ring setting) were changed each day at Wehrmacht and Luftwaffe and changed every two days at the Kriegsmarine. On <a rel="nofollow" class="external text" href="http://users.telenet.be/d.rijmenants/en/enigmaproc.htm">this page</a> you can view some examples of key sheets. So: Internal settings: the selected rotors and their ring setting - in some cases also the reflector - changed every one or two days.

Many Nazi messages sent by non-professionals started or ended with "Heil Hitler!" or "Sieg heil!" in code, either of which offered critical letters for decoding, was about as much cliché as was possible. Such demonstrated loyalty to the Nazi cause -- but also breached the quality of coding. Letters e, i, l, r, s, and t are all very common in German and give away much of the structure of words in the message. <a href="/w/index.php?title=User:Pbrower2a&action=edit&redlink=1" class="new" title="User:Pbrower2a (page does not exist)">Pbrower2a</a> (<a href="/wiki/User_talk:Pbrower2a" title="User talk:Pbrower2a">talk</a>) <a href="https://en.wikipedia.org/wiki/Talk:Enigma_machine#c-Pbrower2a-2013-02-25T10:17:00.000Z-Clarification_request" class="ext-discussiontools-init-timestamplink">10:17, 25 February 2013 (UTC)</a><span id="ooui-php-9" class="ext-discussiontools-init-replybutton oo-ui-widget oo-ui-widget-enabled oo-ui-buttonElement oo-ui-buttonElement-frameless oo-ui-iconElement oo-ui-labelElement oo-ui-flaggedElement-progressive oo-ui-buttonWidget" data-ooui='{"_":"OO.ui.ButtonWidget","rel":["nofollow"],"framed":false,"icon":"share","label":"Reply","flags":["progressive"],"classes":["ext-discussiontools-init-replybutton"]}'><a role="button" tabindex="0" rel="nofollow" class="oo-ui-buttonElement-button">Reply</a> </section><div class="mw-heading mw-heading2 ext-discussiontools-init-section section-heading" onclick="mfTempOpenSection(3)"><h2 id="Inventor" data-mw-thread-id="h-Inventor-2008-11-24T05:46:00.000Z">Inventor</h2> <a role="button" href="/w/index.php?title=Talk:Enigma_machine&action=edit&section=3" title="Edit section: Inventor" class="cdx-button cdx-button--size-large cdx-button--fake-button cdx-button--fake-button--enabled cdx-button--icon-only cdx-button--weight-quiet "> edit </a> <span id='ooui-php-188' class='ext-discussiontools-init-section-overflowMenuButton oo-ui-widget oo-ui-widget-enabled oo-ui-buttonElement oo-ui-buttonElement-frameless oo-ui-iconElement oo-ui-buttonWidget' data-ooui='{"_":"OO.ui.ButtonMenuSelectWidget","rel":["nofollow"],"framed":false,"icon":"ellipsis","data":{"itemConfigs":[{"id":"edit","data":{"id":"edit"},"icon":"edit","label":"Edit"}],"resourceLoaderModules":[]},"classes":["ext-discussiontools-init-section-overflowMenuButton"]}'><a role='button' tabindex='0' rel='nofollow' class='oo-ui-buttonElement-button'></a><div class="ext-discussiontools-init-section-bar"><div class="ext-discussiontools-init-section-metadata">Latest comment: <a href="#c-Vebar-2017-05-25T01:02:00.000Z-Inventor">7 years ago</a>3 comments3 people in discussion</div><div class="ext-discussiontools-init-section-actions"></div></div></div><section class="mf-section-3 collapsible-block" id="mf-section-3"> I have reverted the edit that ascribes the invention of Enigma to Hugo Koch as this is contentious.

Second, German U-boat crews were portrayed in a negative light." <a href="/wiki/User:TedColes" title="User:TedColes">TedColes</a> (<a href="/wiki/User_talk:TedColes" title="User talk:TedColes">talk</a>) <a href="https://en.wikipedia.org/wiki/Talk:Enigma_machine#c-TedColes-2008-12-01T18:05:00.000Z-Matt_Crypto-2008-11-30T16:56:00.000Z" class="ext-discussiontools-init-timestamplink">18:05, 1 December 2008 (UTC)</a><span id="ooui-php-15" class="ext-discussiontools-init-replybutton oo-ui-widget oo-ui-widget-enabled oo-ui-buttonElement oo-ui-buttonElement-frameless oo-ui-iconElement oo-ui-labelElement oo-ui-flaggedElement-progressive oo-ui-buttonWidget" data-ooui='{"_":"OO.ui.ButtonWidget","rel":["nofollow"],"framed":false,"icon":"share","label":"Reply","flags":["progressive"],"classes":["ext-discussiontools-init-replybutton"]}'><a role="button" tabindex="0" rel="nofollow" class="oo-ui-buttonElement-button">Reply</a> <dl><dd>Unless the movie claims to portray reality, is the disclaimer necessary? <a href="/wiki/Special:Contributions/69.135.185.154" title="Special:Contributions/69.135.185.154">69.135.185.154</a> (<a href="/wiki/User_talk:69.135.185.154" title="User talk:69.135.185.154">talk</a>) <a href="https://en.wikipedia.org/wiki/Talk:Enigma_machine#c-69.135.185.154-2009-07-31T01:00:00.000Z-TedColes-2008-12-01T18:05:00.000Z" class="ext-discussiontools-init-timestamplink">01:00, 31 July 2009 (UTC)</a><span id="ooui-php-16" class="ext-discussiontools-init-replybutton oo-ui-widget oo-ui-widget-enabled oo-ui-buttonElement oo-ui-buttonElement-frameless oo-ui-iconElement oo-ui-labelElement oo-ui-flaggedElement-progressive oo-ui-buttonWidget" data-ooui='{"_":"OO.ui.ButtonWidget","rel":["nofollow"],"framed":false,"icon":"share","label":"Reply","flags":["progressive"],"classes":["ext-discussiontools-init-replybutton"]}'><a role="button" tabindex="0" rel="nofollow" class="oo-ui-buttonElement-button">Reply</a></dd></dl></dd></dl></dd></dl> Admittedly the dividing line between fact and fiction is increasingly being blurred these days, but it is relevant to read one review of this film which says: <blockquote>If you believe U-571, Jonathan Mostow's submarine action romp set in the murky depths of World War II, the Americans were instrumental in the capture of the Enigma coding devices, used by the Germans to encrypt top secret messages. The British barely feature in the war effort - it was the good ole Yankee boys leading the way, teaching Hitler a lesson or two with some well-placed torpedoes (the end credits reveal that it was in fact the Brits who captured the Enigma machines and ultimately deciphered the code. Fancy that!). Such glaring lapses in historical accuracy litter Mostow's film, which throws all character and plot development overboard within the first five minutes and goes full steam ahead for sustained action.</blockquote> I still think it appropriate to avoid the possibility of giving offence in this way.--<a href="/wiki/User:TedColes" title="User:TedColes">TedColes</a> (<a href="/wiki/User_talk:TedColes" title="User talk:TedColes">talk</a>) <a href="https://en.wikipedia.org/wiki/Talk:Enigma_machine#c-TedColes-2009-07-31T07:57:00.000Z-U571" class="ext-discussiontools-init-timestamplink">07:57, 31 July 2009 (UTC)</a><span id="ooui-php-17" class="ext-discussiontools-init-replybutton oo-ui-widget oo-ui-widget-enabled oo-ui-buttonElement oo-ui-buttonElement-frameless oo-ui-iconElement oo-ui-labelElement oo-ui-flaggedElement-progressive oo-ui-buttonWidget" data-ooui='{"_":"OO.ui.ButtonWidget","rel":["nofollow"],"framed":false,"icon":"share","label":"Reply","flags":["progressive"],"classes":["ext-discussiontools-init-replybutton"]}'><a role="button" tabindex="0" rel="nofollow" class="oo-ui-buttonElement-button">Reply</a> <dl><dd>Maybe, though I'd be more inclined just to mention that the film exists and is based on capturing an Enigma...if a reader wants to find out more, then they can read the full article on U-571, and find out about the inaccuracies there. <a href="/wiki/User:Matt_Crypto" title="User:Matt Crypto">— Matt Crypto</a> <a href="https://en.wikipedia.org/wiki/Talk:Enigma_machine#c-Matt_Crypto-2009-07-31T08:18:00.000Z-TedColes-2009-07-31T07:57:00.000Z" class="ext-discussiontools-init-timestamplink">08:18, 31 July 2009 (UTC)</a><span id="ooui-php-18" class="ext-discussiontools-init-replybutton oo-ui-widget oo-ui-widget-enabled oo-ui-buttonElement oo-ui-buttonElement-frameless oo-ui-iconElement oo-ui-labelElement oo-ui-flaggedElement-progressive oo-ui-buttonWidget" data-ooui='{"_":"OO.ui.ButtonWidget","rel":["nofollow"],"framed":false,"icon":"share","label":"Reply","flags":["progressive"],"classes":["ext-discussiontools-init-replybutton"]}'><a role="button" tabindex="0" rel="nofollow" class="oo-ui-buttonElement-button">Reply</a></dd></dl> </section><div class="mw-heading mw-heading2 ext-discussiontools-init-section section-heading" onclick="mfTempOpenSection(5)"><h2 id="Image" data-mw-thread-id="h-Image-2008-12-05T19:06:00.000Z">Image</h2> <a role="button" href="/w/index.php?title=Talk:Enigma_machine&action=edit&section=5" title="Edit section: Image" class="cdx-button cdx-button--size-large cdx-button--fake-button cdx-button--fake-button--enabled cdx-button--icon-only cdx-button--weight-quiet "> edit </a> <span id='ooui-php-190' class='ext-discussiontools-init-section-overflowMenuButton oo-ui-widget oo-ui-widget-enabled oo-ui-buttonElement oo-ui-buttonElement-frameless oo-ui-iconElement oo-ui-buttonWidget' data-ooui='{"_":"OO.ui.ButtonMenuSelectWidget","rel":["nofollow"],"framed":false,"icon":"ellipsis","data":{"itemConfigs":[{"id":"edit","data":{"id":"edit"},"icon":"edit","label":"Edit"}],"resourceLoaderModules":[]},"classes":["ext-discussiontools-init-section-overflowMenuButton"]}'><a role='button' tabindex='0' rel='nofollow' class='oo-ui-buttonElement-button'></a><div class="ext-discussiontools-init-section-bar"><div class="ext-discussiontools-init-section-metadata">Latest comment: <a href="#c-TedColes-2011-04-14T15:43:00.000Z-Glrx-2011-04-14T15:33:00.000Z">13 years ago</a>5 comments4 people in discussion</div><div class="ext-discussiontools-init-section-actions"></div></div></div><section class="mf-section-5 collapsible-block" id="mf-section-5"> A new image that may be of some interest: <a href="https://commons.wikimedia.org/wiki/Image:Bundesarchiv_Bild_183-2007-0705-502,_Chiffriermaschine_%22Enigma%22.jpg" class="extiw" title='commons:Image:Bundesarchiv Bild 183-2007-0705-502, Chiffriermaschine "Enigma".jpg'>commons:Image:Bundesarchiv Bild 183-2007-0705-502, Chiffriermaschine "Enigma".jpg</a> -

Karl de Leeuw, a Dutch historian already in 2003 proved that the Enigma was invented by two Dutch navy officers, Spengler and van Hengel. Koch, who was working together with Scherbius. There is no doubt about the solid research and sources of this work of historian de Leeuw, which was published in Cryptologia. His work is acknowledged and confirmed by other historians. I understand that some people are a bit bitten in the **** that their version is fiction, and I understand their err. In those days, the patenting of such machines was a very obscure thing, played in the world of intellingence secrets. More here. Do whatever you want with it, but base your actions (deleting/adding stories) on the work and sources of historians, and don't base them on an opinion. <a rel="nofollow" class="external text" href="http://findarticles.com/p/articles/mi_qa3926/is_200301/ai_n9166984/pg_1">Karl de Leeuw on the invention of the Enigma</a> <a href="/wiki/User:Drdefcom" title="User:Drdefcom">Dirk</a> (<a href="/wiki/User_talk:Drdefcom" title="User talk:Drdefcom">talk</a>) <a href="https://en.wikipedia.org/wiki/Talk:Enigma_machine#c-Drdefcom-2008-12-19T15:37:00.000Z-Scherbius_and_Koch_discussion" class="ext-discussiontools-init-timestamplink">15:37, 19 December 2008 (UTC)</a><span id="ooui-php-24" class="ext-discussiontools-init-replybutton oo-ui-widget oo-ui-widget-enabled oo-ui-buttonElement oo-ui-buttonElement-frameless oo-ui-iconElement oo-ui-labelElement oo-ui-flaggedElement-progressive oo-ui-buttonWidget" data-ooui='{"_":"OO.ui.ButtonWidget","rel":["nofollow"],"framed":false,"icon":"share","label":"Reply","flags":["progressive"],"classes":["ext-discussiontools-init-replybutton"]}'><a role="button" tabindex="0" rel="nofollow" class="oo-ui-buttonElement-button">Reply</a> <dl><dd>Indeed, Spengler and van Hengel are now known to have come up with the first rotor machines (as far as we know), but that doesn't mean they invented Enigma, which was a specific family of rotor machines.

That later article is a correction of the 1999 article, not the other way around! They did invent the machine. Of course, it was scherbius that named it Enigma, but who named it how is not the discussion. The simple fact is that the machine that was later called Enigma is invented by the two Dutch naval officers. No more no less. Saying that Scherbius made the Enigma is the same as commercialising a DW (Disk with Music) but actually produce a CD.

The Poles themselves realised very quickly that the plug board did not affect their ability to find potential machine settings from the double indicator. Once a potential key setting was found, the plugboard merely turned the otherwise legible German into a partial simple substitution cypher. A simple substitution cypher is virtually child's play to analyse. The Germans continued to hold the view that the plugboard would severely hamper analysis of the machine, precisely because it would disguise a successful attempt by not immediately revealing readable German. The reality was, because of the Poles' realisation of its effects, that it was hardly any impediment at all.</dd></dl> <dl><dd>One of the frustrations of cryptoanalysis is that there is absolutely no sense of being close to finding the solution. You either have the answer - or you don't. The idea behind the plugboard was that if the code breakers thought they might have a solution, the fact that they were not reading German would make them believe that they had not got the solution after all. The reality was that the code breakers already knew that the text they were looking for was German encyphered by a simple substitution cypher (the plugboard) which negated the security it was meant to provide. The addition of more plugboard leads was to disguise the plain text more effectively. The basic idea of adding a cryptographically very weak substitution cypher (something no military grade cypher system would normally consider) on top of a cryptographically strong system like Enigma might have succeeded in delaying or preventing its analysis had it not been rumbled so early on. The fact that it was only a partial substitution made it stand out. Had the Germans used 13 plugboard leads right from the start, things may have been very different. <a href="/wiki/User:DieSwartzPunkt" title="User:DieSwartzPunkt">DieSwartzPunkt</a> (<a href="/wiki/User_talk:DieSwartzPunkt" title="User talk:DieSwartzPunkt">talk</a>) <a href="https://en.wikipedia.org/wiki/Talk:Enigma_machine#c-DieSwartzPunkt-2013-06-21T13:20:00.000Z-50.98.214.216-2011-08-03T14:32:00.000Z" class="ext-discussiontools-init-timestamplink">13:20, 21 June 2013 (UTC)</a><span id="ooui-php-31" class="ext-discussiontools-init-replybutton oo-ui-widget oo-ui-widget-enabled oo-ui-buttonElement oo-ui-buttonElement-frameless oo-ui-iconElement oo-ui-labelElement oo-ui-flaggedElement-progressive oo-ui-buttonWidget" data-ooui='{"_":"OO.ui.ButtonWidget","rel":["nofollow"],"framed":false,"icon":"share","label":"Reply","flags":["progressive"],"classes":["ext-discussiontools-init-replybutton"]}'><a role="button" tabindex="0" rel="nofollow" class="oo-ui-buttonElement-button">Reply</a></dd></dl> <dl><dd><dl><dd>I'll second DSP; the plugboard was an illusion of security.

The rules and essentials has not been changed, only the level of complexity was increasing, what caused much more possible combinations and hence required much more (complex and faster) devices to break it, so British were doing this. — Preceding <a href="/wiki/Wikipedia:Signatures" title="Wikipedia:Signatures">unsigned</a> comment added by <a href="/wiki/Special:Contributions/83.27.208.66" title="Special:Contributions/83.27.208.66">83.27.208.66</a> (<a href="/w/index.php?title=User_talk:83.27.208.66&action=edit&redlink=1" class="new" title="User talk:83.27.208.66 (page does not exist)">talk</a>) <a href="https://en.wikipedia.org/wiki/Talk:Enigma_machine#c-83.27.208.66-2013-06-24T22:40:00.000Z-TedColes-2012-12-09T14:11:00.000Z" class="ext-discussiontools-init-timestamplink">22:40, 24 June 2013 (UTC)</a><span id="ooui-php-42" class="ext-discussiontools-init-replybutton oo-ui-widget oo-ui-widget-enabled oo-ui-buttonElement oo-ui-buttonElement-frameless oo-ui-iconElement oo-ui-labelElement oo-ui-flaggedElement-progressive oo-ui-buttonWidget" data-ooui='{"_":"OO.ui.ButtonWidget","rel":["nofollow"],"framed":false,"icon":"share","label":"Reply","flags":["progressive"],"classes":["ext-discussiontools-init-replybutton"]}'><a role="button" tabindex="0" rel="nofollow" class="oo-ui-buttonElement-button">Reply</a> <dl><dd>The articles <a href="/wiki/Cryptanalysis_of_the_Enigma" title="Cryptanalysis of the Enigma">Cryptanalysis of the Enigma</a> and <a href="/wiki/Biuro_Szyfr%C3%B3w" class="mw-redirect" title="Biuro Szyfrów">Biuro Szyfrów</a> describe the pioneering Polish work on the breaking of Enigma.

Because this Enigma machine, breaking the code by Polish, and continuation of their work in Bletchley Park was the reason Nazists has lost the WWII and our world is in the shape we know it. Therefore this facts must not be omitted. Of course a separate article can be reasonable (I think I will do it in the nearest free time). Anyway consequences of breaking code are equally (or even more) important then technical details. Problem with sources implies from fact that that was one of most top secret of WWII, without it Germans would change and it would be meaningless. So in many sources this facts are omitted not because POV but because many authors are not aware of real true, as it was long time hidden as deeply as possible. After WWII Poland were "silently occupied" by Soviet Union and in this situation alive Enigma codebreakers had to keep silence if they wanted not to be sentenced to death for cooperation with "Western Imperialists" or lost their life in any other way by "unknown assassins" from <a href="/wiki/KGB" title="KGB">KGB</a>. And for a long time after war truth about Enigma was top secret still. For many, many reasons: eg. Churchill was aware London is to be bombed, with details were when - but could not take countermeasures without compromising the source - broken Enigma code. And also there were several other big war operations which were influenced by Enigma, I think making a list of them may change understanding of "what&why" in some parts of WWII. Also US were benefiting for some intelligence info, but the source were never unveiled. That, to keep broken Enigma code in secret, cost British many lifes lost, but has saved other lifes and was the most essential reason of victory in WWII - Churchill has admitted this. Polish were aware of this from the beginning before WWII has broke out, that is why they passed this to French and British (who were not believe that time that Polish has broken Enigma code) - they were aware the time is coming. Hitler has lost WWII when Enigma was broken, in 1932.</dd> <dd>My point is that this article ought to be balanced as for many readers this will be basic source of knowledge about Enigma case. Hence technical details are not the only important things about it. Of course they are important and well written - but this is not enough. Rule of reasonable compromise. The sources is a question of spare/free time I will have. — Preceding <a href="/wiki/Wikipedia:Signatures" title="Wikipedia:Signatures">unsigned</a> comment added by <a href="/wiki/Special:Contributions/83.26.234.112" title="Special:Contributions/83.26.234.112">83.26.234.112</a> (<a href="/w/index.php?title=User_talk:83.26.234.112&action=edit&redlink=1" class="new" title="User talk:83.26.234.112 (page does not exist)">talk</a>) <a href="https://en.wikipedia.org/wiki/Talk:Enigma_machine#c-83.26.234.112-2013-06-25T10:39:00.000Z-TedColes-2013-06-25T07:16:00.000Z" class="ext-discussiontools-init-timestamplink">10:39, 25 June 2013 (UTC)</a><span id="ooui-php-44" class="ext-discussiontools-init-replybutton oo-ui-widget oo-ui-widget-enabled oo-ui-buttonElement oo-ui-buttonElement-frameless oo-ui-iconElement oo-ui-labelElement oo-ui-flaggedElement-progressive oo-ui-buttonWidget" data-ooui='{"_":"OO.ui.ButtonWidget","rel":["nofollow"],"framed":false,"icon":"share","label":"Reply","flags":["progressive"],"classes":["ext-discussiontools-init-replybutton"]}'><a role="button" tabindex="0" rel="nofollow" class="oo-ui-buttonElement-button">Reply</a></dd></dl></dd></dl></dd></dl></dd></dl></dd></dl> <dl><dd><dl><dd><dl><dd><dl><dd><dl><dd><dl><dd>There is no evidence that the breaking of Enigma (and Lorenz) is the reason that Germany lost the war. There are many factors to consider. The view that is most widely held is that the Bletchley codebreakers probably shortened the war by two years. That is all that can be said. It cannot be stated with any certainty who the victor would have been had the war followed its course. Germany may well have succeeded in developing the atomic bomb or may have succeeded in perfecting their long range ballistic missiles (designed to take the war to America). Someone may have succeeded in assasinating Hitler ending the war by another route. No one is in any position to second guess how things would have turned out but for the activities of Bletchley Park and others. <a href="/wiki/User:DieSwartzPunkt" title="User:DieSwartzPunkt">DieSwartzPunkt</a> (<a href="/wiki/User_talk:DieSwartzPunkt" title="User talk:DieSwartzPunkt">talk</a>) <a href="https://en.wikipedia.org/wiki/Talk:Enigma_machine#c-DieSwartzPunkt-2013-06-26T10:08:00.000Z-83.26.234.112-2013-06-25T10:39:00.000Z" class="ext-discussiontools-init-timestamplink">10:08, 26 June 2013 (UTC)</a><span id="ooui-php-45" class="ext-discussiontools-init-replybutton oo-ui-widget oo-ui-widget-enabled oo-ui-buttonElement oo-ui-buttonElement-frameless oo-ui-iconElement oo-ui-labelElement oo-ui-flaggedElement-progressive oo-ui-buttonWidget" data-ooui='{"_":"OO.ui.ButtonWidget","rel":["nofollow"],"framed":false,"icon":"share","label":"Reply","flags":["progressive"],"classes":["ext-discussiontools-init-replybutton"]}'><a role="button" tabindex="0" rel="nofollow" class="oo-ui-buttonElement-button">Reply</a></dd></dl></dd></dl></dd></dl></dd></dl></dd></dl></dd></dl> <dl><dd><dl><dd><dl><dd><dl><dd>It has to be noted that although both the Poles and British employed machines known as Bombes (regardless of how they spelt or pronounced them), the two machines although they operated on the same basic principle, in fact operated in very different ways. The Polish machine exploited a procedural flaw in the way the Enigma machine was used, the double encryption of the individual message key where the machine searched for rotor settings where the transmitted six letter group decrypted to a repeated three letter group. The setting was not unique for any transmitted group, so it was necesary to try each possiblility as it was found.</dd></dl></dd></dl></dd></dl></dd></dl> <dl><dd><dl><dd><dl><dd><dl><dd>The British machines would not have been able to operate this way as the double encryption had been abandoned before their bombes had been developed. Instead, the British machines exploited two systematic flaws that had been discovered in the way that the enigma worked coupled with a procedural flaw in the way it was used. The first systematic flaw was known from when the Poles first intercepted the commercial Enigma back in 1929. It was immediately known that Enigma would never encrypt any letter as itself. The procedural flaw was that German operators resorted to using jargon when assembling their messages. This allowed the codebreakers to engineer a situation for the signal units to report which they would do with predictable phrases and wording (this was known as "gardening"). The British were able to compare the received message with the megssage that they predicted the Gemans would send. If they found an alignment where none of the letters matched, then there was more than a sporting chance that the received message was the encrypted version of the plain text.</dd></dl></dd></dl></dd></dl></dd></dl> <dl><dd><dl><dd><dl><dd><dl><dd>Through examination of these messages, the British had noticed that the Enigma was exhibiting a phenomenon dubbed as circular encryption (the second systematic flaw). In a fragment of message, when the plain text is compared to the cypher text, it was found that (say) a 'G' was encrypted as a 'T' at one point in the text. Later in the same fragment a 'T' was encrypted as a 'G'. Although such a feature was a possibility in any message fragment, the British realised that it occured vastly more frequently than probability dictated that it should have done. Another example of this circular encryption is where (say) a 'K' would be encrypted as a 'D'. Further on a 'D' would be encrypted as a 'S'. Further still an 'S' was encrypted as a 'K', giving a circle of three. The larger circles were preferred because although their occurence were a little rarer they significantly reduced the possible settings where the bombe would report a viable setting. As the codebreakers examined messages they looked for these relationships over a number of messages from the same theatre. These relationships were used to produce a 'menu' for the bombes. What the bombes then did was search for those rotor positions where all the circular encryptions found in the messages were possible. To be strictly accurate, Turring's view on what the bombes did was to eliminate all the rotor positions and settings that would not produce all the found circular encryptions. As each possibility was found, it was tested on a British Type X machine (a machine functionally the same as an Enigma that printed its output on paper tape). Once the minor inconvenience of the plugboard was circumvented and German was printed out, all the other messages from the same theatre (which used the same settings) could then be decrypted. <a href="/wiki/User:DieSwartzPunkt" title="User:DieSwartzPunkt">DieSwartzPunkt</a> (<a href="/wiki/User_talk:DieSwartzPunkt" title="User talk:DieSwartzPunkt">talk</a>) <a href="https://en.wikipedia.org/wiki/Talk:Enigma_machine#c-DieSwartzPunkt-2013-06-25T11:14:00.000Z-83.27.208.66-2013-06-24T22:40:00.000Z" class="ext-discussiontools-init-timestamplink">11:14, 25 June 2013 (UTC)</a><span id="ooui-php-46" class="ext-discussiontools-init-replybutton oo-ui-widget oo-ui-widget-enabled oo-ui-buttonElement oo-ui-buttonElement-frameless oo-ui-iconElement oo-ui-labelElement oo-ui-flaggedElement-progressive oo-ui-buttonWidget" data-ooui='{"_":"OO.ui.ButtonWidget","rel":["nofollow"],"framed":false,"icon":"share","label":"Reply","flags":["progressive"],"classes":["ext-discussiontools-init-replybutton"]}'><a role="button" tabindex="0" rel="nofollow" class="oo-ui-buttonElement-button">Reply</a></dd></dl></dd></dl></dd></dl></dd></dl> Please see also my comment under "Polish Contribution" in this talk page. <a href="/wiki/Special:Contributions/108.222.214.13" title="Special:Contributions/108.222.214.13">108.222.214.13</a> (<a href="/w/index.php?title=User_talk:108.222.214.13&action=edit&redlink=1" class="new" title="User talk:108.222.214.13 (page does not exist)">talk</a>) <a href="https://en.wikipedia.org/wiki/Talk:Enigma_machine#c-108.222.214.13-2013-07-20T19:05:00.000Z-Poles" class="ext-discussiontools-init-timestamplink">19:05, 20 July 2013 (UTC)</a><span id="ooui-php-47" class="ext-discussiontools-init-replybutton oo-ui-widget oo-ui-widget-enabled oo-ui-buttonElement oo-ui-buttonElement-frameless oo-ui-iconElement oo-ui-labelElement oo-ui-flaggedElement-progressive oo-ui-buttonWidget" data-ooui='{"_":"OO.ui.ButtonWidget","rel":["nofollow"],"framed":false,"icon":"share","label":"Reply","flags":["progressive"],"classes":["ext-discussiontools-init-replybutton"]}'><a role="button" tabindex="0" rel="nofollow" class="oo-ui-buttonElement-button">Reply</a> </section><div class="mw-heading mw-heading2 ext-discussiontools-init-section section-heading" onclick="mfTempOpenSection(10)"><h2 id="The_second_paragraph_is_poorly_written,_and_here's_why:" data-mw-thread-id="h-The_second_paragraph_is_poorly_written,_and_here's_why:-2009-06-27T03:41:00.000Z">The second paragraph is poorly written, and here's why:</h2> <a role="button" href="/w/index.php?title=Talk:Enigma_machine&action=edit&section=10" title="Edit section: The second paragraph is poorly written, and here's why:" class="cdx-button cdx-button--size-large cdx-button--fake-button cdx-button--fake-button--enabled cdx-button--icon-only cdx-button--weight-quiet "> edit </a> <span id='ooui-php-195' class='ext-discussiontools-init-section-overflowMenuButton oo-ui-widget oo-ui-widget-enabled oo-ui-buttonElement oo-ui-buttonElement-frameless oo-ui-iconElement oo-ui-buttonWidget' data-ooui='{"_":"OO.ui.ButtonMenuSelectWidget","rel":["nofollow"],"framed":false,"icon":"ellipsis","data":{"itemConfigs":[{"id":"edit","data":{"id":"edit"},"icon":"edit","label":"Edit"}],"resourceLoaderModules":[]},"classes":["ext-discussiontools-init-section-overflowMenuButton"]}'><a role='button' tabindex='0' rel='nofollow' class='oo-ui-buttonElement-button'></a><div class="ext-discussiontools-init-section-bar"><div class="ext-discussiontools-init-section-metadata">Latest comment: <a href="#c-108.222.214.13-2013-07-20T19:05:00.000Z-The_second_paragraph_is_poorly_written,_and_here's_why:">11 years ago</a>4 comments4 people in discussion</div><div class="ext-discussiontools-init-section-actions"></div></div></div><section class="mf-section-10 collapsible-block" id="mf-section-10"> It presently reads as follows: <ul><li>The machine has become well-known because Allied codebreakers were able to decrypt a vast number of messages which had been enciphered using the Enigma.

Next, he transmitted the start position, WZA, the encoded message key, UHL, and then the ciphertext.</dd></dl> <a href="/wiki/User:Tuntable" title="User:Tuntable">Tuntable</a> (<a href="/wiki/User_talk:Tuntable" title="User talk:Tuntable">talk</a>) <a href="https://en.wikipedia.org/wiki/Talk:Enigma_machine#c-Tuntable-2009-07-30T00:31:00.000Z-The_following_must_be_wrong_(under_Indicators)" class="ext-discussiontools-init-timestamplink">00:31, 30 July 2009 (UTC)</a><span id="ooui-php-52" class="ext-discussiontools-init-replybutton oo-ui-widget oo-ui-widget-enabled oo-ui-buttonElement oo-ui-buttonElement-frameless oo-ui-iconElement oo-ui-labelElement oo-ui-flaggedElement-progressive oo-ui-buttonWidget" data-ooui='{"_":"OO.ui.ButtonWidget","rel":["nofollow"],"framed":false,"icon":"share","label":"Reply","flags":["progressive"],"classes":["ext-discussiontools-init-replybutton"]}'><a role="button" tabindex="0" rel="nofollow" class="oo-ui-buttonElement-button">Reply</a> <dl><dd>The secret was "the rotors, their ring settings and the plugboard". <a href="/wiki/User:Matt_Crypto" title="User:Matt Crypto">— Matt Crypto</a> <a href="https://en.wikipedia.org/wiki/Talk:Enigma_machine#c-Matt_Crypto-2009-07-30T07:20:00.000Z-Tuntable-2009-07-30T00:31:00.000Z" class="ext-discussiontools-init-timestamplink">07:20, 30 July 2009 (UTC)</a><span id="ooui-php-53" class="ext-discussiontools-init-replybutton oo-ui-widget oo-ui-widget-enabled oo-ui-buttonElement oo-ui-buttonElement-frameless oo-ui-iconElement oo-ui-labelElement oo-ui-flaggedElement-progressive oo-ui-buttonWidget" data-ooui='{"_":"OO.ui.ButtonWidget","rel":["nofollow"],"framed":false,"icon":"share","label":"Reply","flags":["progressive"],"classes":["ext-discussiontools-init-replybutton"]}'><a role="button" tabindex="0" rel="nofollow" class="oo-ui-buttonElement-button">Reply</a></dd></dl> <a href="/w/index.php?title=User:Computerramjet&action=edit&redlink=1" class="new" title="User:Computerramjet (page does not exist)">Computerramjet</a> (<a href="/wiki/User_talk:Computerramjet" title="User talk:Computerramjet">talk</a>) <a href="https://en.wikipedia.org/wiki/Talk:Enigma_machine#c-Computerramjet-2015-01-04T20:19:00.000Z-The_following_must_be_wrong_(under_Indicators)" class="ext-discussiontools-init-timestamplink">20:19, 4 January 2015 (UTC)</a><span id="ooui-php-54" class="ext-discussiontools-init-replybutton oo-ui-widget oo-ui-widget-enabled oo-ui-buttonElement oo-ui-buttonElement-frameless oo-ui-iconElement oo-ui-labelElement oo-ui-flaggedElement-progressive oo-ui-buttonWidget" data-ooui='{"_":"OO.ui.ButtonWidget","rel":["nofollow"],"framed":false,"icon":"share","label":"Reply","flags":["progressive"],"classes":["ext-discussiontools-init-replybutton"]}'><a role="button" tabindex="0" rel="nofollow" class="oo-ui-buttonElement-button">Reply</a> <dl><dd>I stumbled with this as well.

At first, the idea of transmitting the random indicator setting in clear text seemed to be completely insecure, but as Tuntable states, the rotors, rings and plugboard are still secret so there is still a 'daily key' although with a shorter effective key length. However, since the random indicator is only used to encode a short random message key, it would make it harder to decipher the 'daily key', so maybe the shorter effective key length wasn't viewed as a problem. It would be nice if someone could clarify the indicator procedure and discuss the issues associated with transmitting the random indicator setting in clear text. Also, how did this new procedure impact the bombe? From what I understand the bombe required longer cribs to create loops in the menu. That wouldn't work for short random message keys, so did the bombe determine the daily key (without a global initial position) and the message key (initial setting), and then only the daily key would be used to decode other messages?</dd></dl> The setting used by hobbists from 1970-1985 to receive feeds from reuters, etc, was REDRUM. —Preceding <a href="/wiki/Wikipedia:Signatures" title="Wikipedia:Signatures">unsigned</a> comment added by <a href="/wiki/Special:Contributions/71.134.243.171" title="Special:Contributions/71.134.243.171">71.134.243.171</a> (<a href="/w/index.php?title=User_talk:71.134.243.171&action=edit&redlink=1" class="new" title="User talk:71.134.243.171 (page does not exist)">talk</a>) <a href="https://en.wikipedia.org/wiki/Talk:Enigma_machine#c-71.134.243.171-2010-04-23T06:02:00.000Z-The_following_must_be_wrong_(under_Indicators)" class="ext-discussiontools-init-timestamplink">06:02, 23 April 2010 (UTC)</a><span id="ooui-php-55" class="ext-discussiontools-init-replybutton oo-ui-widget oo-ui-widget-enabled oo-ui-buttonElement oo-ui-buttonElement-frameless oo-ui-iconElement oo-ui-labelElement oo-ui-flaggedElement-progressive oo-ui-buttonWidget" data-ooui='{"_":"OO.ui.ButtonWidget","rel":["nofollow"],"framed":false,"icon":"share","label":"Reply","flags":["progressive"],"classes":["ext-discussiontools-init-replybutton"]}'><a role="button" tabindex="0" rel="nofollow" class="oo-ui-buttonElement-button">Reply</a> </section><div class="mw-heading mw-heading2 ext-discussiontools-init-section section-heading" onclick="mfTempOpenSection(12)"><h2 id="Decoding" data-mw-thread-id="h-Decoding-2009-11-17T15:27:00.000Z">Decoding</h2> <a role="button" href="/w/index.php?title=Talk:Enigma_machine&action=edit&section=12" title="Edit section: Decoding" class="cdx-button cdx-button--size-large cdx-button--fake-button cdx-button--fake-button--enabled cdx-button--icon-only cdx-button--weight-quiet "> edit </a> <span id='ooui-php-197' class='ext-discussiontools-init-section-overflowMenuButton oo-ui-widget oo-ui-widget-enabled oo-ui-buttonElement oo-ui-buttonElement-frameless oo-ui-iconElement oo-ui-buttonWidget' data-ooui='{"_":"OO.ui.ButtonMenuSelectWidget","rel":["nofollow"],"framed":false,"icon":"ellipsis","data":{"itemConfigs":[{"id":"edit","data":{"id":"edit"},"icon":"edit","label":"Edit"}],"resourceLoaderModules":[]},"classes":["ext-discussiontools-init-section-overflowMenuButton"]}'><a role='button' tabindex='0' rel='nofollow' class='oo-ui-buttonElement-button'></a><div class="ext-discussiontools-init-section-bar"><div class="ext-discussiontools-init-section-metadata">Latest comment: <a href="#c-TedColes-2009-11-18T06:22:00.000Z-Matt_Crypto-2009-11-17T16:18:00.000Z">15 years ago</a>3 comments3 people in discussion</div><div class="ext-discussiontools-init-section-actions"></div></div></div><section class="mf-section-12 collapsible-block" id="mf-section-12"> So how were the messages decoded (assuming one had the codebooks or equivalent)?

They were second in the field and agreed, and kept to the agreement, to play second fiddle and so naturally the people they put into their German machine cryptography were not the best cryptographers they had, but rather efficient and intelligent organizers with cryptographic knowledge. </blockquote></dd> <dd>And p. 91:<blockquote> The acceptance by Op-20-G of the principle of pooled bombe resources was a fairly slow one. … By the time the Second Front opened very close and efficient cooperation existed. Priorities of keys were decided at weekly meetings at which the U.S.N. representative was present and Op-20-G stuck most loyally to the priorities as laid down, running a vast number of Hut 6 jobs and enabling them to break keys which would have otherwise have remained unbroken. I think it is a considerable tribute to the good sense of all parties concerned, and most especially to Op-20-G who were in a somewhat irksome position, that relations were at all times extremely cordial and that it was possible to get so much work so efficiently done when the machinery had to be shared by 3 groups of people, each feeling at heart that their own particular problem was the one which really mattered. </blockquote></dd> <dd>For the US Army's considerable contribution, I would refer to: <a rel="nofollow" class="external text" href="http://www.codesandciphers.org.uk/documents/bmbrpt/bmbpg046.htm">The US 6812 Division Bombe Report Eastcote 1944</a></dd> <dd>--<a href="/wiki/User:TedColes" title="User:TedColes">TedColes</a> (<a href="/wiki/User_talk:TedColes" title="User talk:TedColes">talk</a>) <a href="https://en.wikipedia.org/wiki/Talk:Enigma_machine#c-TedColes-2010-04-13T09:41:00.000Z-Matt_Crypto-2010-04-12T21:56:00.000Z" class="ext-discussiontools-init-timestamplink">09:41, 13 April 2010 (UTC)</a><span id="ooui-php-66" class="ext-discussiontools-init-replybutton oo-ui-widget oo-ui-widget-enabled oo-ui-buttonElement oo-ui-buttonElement-frameless oo-ui-iconElement oo-ui-labelElement oo-ui-flaggedElement-progressive oo-ui-buttonWidget" data-ooui='{"_":"OO.ui.ButtonWidget","rel":["nofollow"],"framed":false,"icon":"share","label":"Reply","flags":["progressive"],"classes":["ext-discussiontools-init-replybutton"]}'><a role="button" tabindex="0" rel="nofollow" class="oo-ui-buttonElement-button">Reply</a></dd></dl></dd></dl> </section><div class="mw-heading mw-heading2 ext-discussiontools-init-section section-heading" onclick="mfTempOpenSection(15)"><h2 id="Polish_contribution" data-mw-thread-id="h-Polish_contribution-2010-04-12T16:51:00.000Z">Polish contribution</h2> <a role="button" href="/w/index.php?title=Talk:Enigma_machine&action=edit&section=15" title="Edit section: Polish contribution" class="cdx-button cdx-button--size-large cdx-button--fake-button cdx-button--fake-button--enabled cdx-button--icon-only cdx-button--weight-quiet "> edit </a> <span id='ooui-php-200' class='ext-discussiontools-init-section-overflowMenuButton oo-ui-widget oo-ui-widget-enabled oo-ui-buttonElement oo-ui-buttonElement-frameless oo-ui-iconElement oo-ui-buttonWidget' data-ooui='{"_":"OO.ui.ButtonMenuSelectWidget","rel":["nofollow"],"framed":false,"icon":"ellipsis","data":{"itemConfigs":[{"id":"edit","data":{"id":"edit"},"icon":"edit","label":"Edit"}],"resourceLoaderModules":[]},"classes":["ext-discussiontools-init-section-overflowMenuButton"]}'><a role='button' tabindex='0' rel='nofollow' class='oo-ui-buttonElement-button'></a><div class="ext-discussiontools-init-section-bar"><div class="ext-discussiontools-init-section-metadata">Latest comment: <a href="#c-108.222.214.13-2013-07-20T18:55:00.000Z-Polish_contribution">11 years ago</a>3 comments2 people in discussion</div><div class="ext-discussiontools-init-section-actions"></div></div></div><section class="mf-section-15 collapsible-block" id="mf-section-15"> <a href="/wiki/Vumba" class="mw-redirect" title="Vumba">Vumba</a> says that 'the "Bomba" was a Polish decrypt machine later enhanced by the British.' I don't agree that this is a good reflection of the reality. Budiansky (2000), and others point out that Alan Turing developed the idea of a machine that the Bomba represented, but worked on an entirely different premise. To quote Budiansky:<a href="#cite_note-1">[1]</a> <blockquote>The Bomba had very limited applicability. It depended on there being three doubly enciphered indicators in which the same letter was repeated in all three; it also would work only if that repeated letter happened to be unsteckered, so its true identity was known. But with a text crib Turing at once saw that a series of Enigmas could be linked together in a different architecture to perform an automated search. And it would be an incredibly powerful method.</blockquote> We do indeed "need to stay with the facts here".--<a href="/wiki/User:TedColes" title="User:TedColes">TedColes</a> (<a href="/wiki/User_talk:TedColes" title="User talk:TedColes">talk</a>) <a href="https://en.wikipedia.org/wiki/Talk:Enigma_machine#c-TedColes-2010-04-12T16:51:00.000Z-Polish_contribution" class="ext-discussiontools-init-timestamplink">16:51, 12 April 2010 (UTC)</a><span id="ooui-php-67" class="ext-discussiontools-init-replybutton oo-ui-widget oo-ui-widget-enabled oo-ui-buttonElement oo-ui-buttonElement-frameless oo-ui-iconElement oo-ui-labelElement oo-ui-flaggedElement-progressive oo-ui-buttonWidget" data-ooui='{"_":"OO.ui.ButtonWidget","rel":["nofollow"],"framed":false,"icon":"share","label":"Reply","flags":["progressive"],"classes":["ext-discussiontools-init-replybutton"]}'><a role="button" tabindex="0" rel="nofollow" class="oo-ui-buttonElement-button">Reply</a> It is, perhaps, worth quoting <a href="/wiki/Peter_Calvocoressi" title="Peter Calvocoressi">Peter Calvocoressi</a>, who became head of the Luftwaffe section in Hut 3, who wrote in commenting on the Polish contribution: <style data-mw-deduplicate="TemplateStyles:r1244412712">.mw-parser-output .templatequote{overflow:hidden;margin:1em 0;padding:0 32px}.mw-parser-output .templatequotecite{line-height:1.5em;text-align:left;margin-top:0}@media(min-width:500px){.mw-parser-output .templatequotecite{padding-left:1.6em}}</style><blockquote class="templatequote">The one moot point is - how valuable?

Without using Różycki, Rejewski, Zygalski techniques breaking cyphertext would not be possible, as those are mathemathical methodology. It can't be different. If it would be this would not be Enigma code. Just like for addition you must make operation of additing, and nothing else work for addition, no meter "how enlightened you would be". This is thanks to polish mathematical school (meaning group of intellectuals from Lvov (pol. Lwów) <a href="/wiki/Lw%C3%B3w_School_of_Mathematics" title="Lwów School of Mathematics">Lwów School of Mathematics</a> and their works far forward then others that time eg. <a href="/wiki/Banach" title="Banach">Banach</a>, <a href="/wiki/Hugo_Steinhaus" title="Hugo Steinhaus">Hugo Steinhaus</a>, <a href="/wiki/Stanis%C5%82aw_Mazur" title="Stanisław Mazur">Stanisław Mazur</a>, <a href="/wiki/Stanislaw_Ulam" class="mw-redirect" title="Stanislaw Ulam">Stanislaw Ulam</a>. For this reason Turing was needed to understand this staff, common military personnel was not educated enough (or at all) in high mathematics. People don't like to admit they don't understand how it works - try yourself do you understand mathematical foundations of breaking Enigma codes? Quite well documented in Wikipedia even? It was easier to omit Polish contribution then to admit "we didn't understand what they were talking about", so Turing was a very good person as a genius to point him as inventor, but it is not true. British intelligence to admit that the most secret code of WWII was broken from 1932 by "wild Poles from somewhere wild place far far away"? And they didn't stop Hitler much sooner? How they would look? It was easier to omit Polish, and more beneficial. Second: for political reasons British wanted to avoid as only possible to show Poles for not to annoying Soviet Union, which were occupied Poland after Yalta pact.</dd></dl></dd></dl></dd></dl> (Previous Comment Unsigned) As someone completely impartial to the article (this is my first time even reading it), I must say that the second introductory paragraph as of <a class="external text" href="https://en.wikipedia.org/w/index.php?title=Enigma_machine&oldid=564026049">July 20th, 2013</a> is excessively redundant regarding the Polish contribution, and looks as though there may be some bias at work in editing by <a href="/wiki/Special:Contributions/83.27.208.66" title="Special:Contributions/83.27.208.66">83.27.208.66</a> (which is, incidentally, a Polish IP address).

OP-20-G had apparently made significant progress on the new code by October 1940. In late 1940, the Japanese introduced JN-25. (Prado, p 80.)

That was mistake and caused protests but they were not hear there. "Achieving very little success" by Polish intelligence mean that from 1932 till break of WWII they were reading all trade cyphertexts and most of military cyphertexts. Limitation was by the number of people employed for this - as the more people then the worse for keep the things in secret. Finally they were not decrypting all cyphertexts they have, but trying to select the most important. Remember those works required manual work and computers were not aviable that time. But that was enough of knowledge to make them to decide to make a gift of broken Enigma code, cryptological bomb, devices and all the theoretical stuff to both British and French intelligence before WWII and to destroy everything located in Poland what could show secret, whole complex including buildings, basemants etc. was blown up after evacuation, before Germans have entered.

Although the British cryptanalysts did have their own operation in attempting to break Enigma, it was for a long time, way behind the Polish efforts. When the Poles decided to hand over everything they had, the British found that surprise was not adequate to express what the the Poles had achieved. They were forced to resort to astonishment. Although the Poles had fallen behind by the time of the hand over (largely because time was against them), their contribution to the future of Enigma intercepts was crucial. It is perhaps nothing short of a great shame that the Polish crytanalysts were frozen out of future code breaking activity. Who knows what might have been achieved if they had been permitted to participate? There is no doubt that in other areas where the Poles supported allied efforts in the war that were very effective indeed (e.g. in the Polish squadrons of the RAF where the British commanders could scarcely believe the rate at which the Poles were shooting down German aircraft - until they went and had a look for themselves and were also forced to resort to astonishment!). <a href="/wiki/Special:Contributions/86.186.10.125" title="Special:Contributions/86.186.10.125">86.186.10.125</a> (<a href="/w/index.php?title=User_talk:86.186.10.125&action=edit&redlink=1" class="new" title="User talk:86.186.10.125 (page does not exist)">talk</a>) <a href="https://en.wikipedia.org/wiki/Talk:Enigma_machine#c-86.186.10.125-2013-06-26T18:03:00.000Z-83.26.234.112-2013-06-25T11:31:00.000Z" class="ext-discussiontools-init-timestamplink">18:03, 26 June 2013 (UTC)</a><span id="ooui-php-90" class="ext-discussiontools-init-replybutton oo-ui-widget oo-ui-widget-enabled oo-ui-buttonElement oo-ui-buttonElement-frameless oo-ui-iconElement oo-ui-labelElement oo-ui-flaggedElement-progressive oo-ui-buttonWidget" data-ooui='{"_":"OO.ui.ButtonWidget","rel":["nofollow"],"framed":false,"icon":"share","label":"Reply","flags":["progressive"],"classes":["ext-discussiontools-init-replybutton"]}'><a role="button" tabindex="0" rel="nofollow" class="oo-ui-buttonElement-button">Reply</a></dd></dl></dd></dl></dd></dl> <dl><dd><dl><dd><dl><dd><dl><dd>Do we know why the British were so reluctant to allow the Polish codebreakers to continue their efforts?

Rejewski may believe that Poland would have shared Enigma secrets even without a national emergency, but Rejewski was probably not involved in that decision process. Some of the great decisions of the Polish Cipher Bureau were to keep information from the mathematicians, so the the mathematicians were not in all the loops. Britain made even greater decisions in its willingness to invest in breaking the codes.

Germany invaded and quickly overran Poland in 1939. The Cipher Bureau was attached to the General Staff, and it evacuated. Eventually, the Cipher Bureau crossed into Romania. The uniformed officers were separated from the civilian codebreakers (RRZ) at the border. The civilians were told to make their way to a specific loccation, but instead they jumped on a train and went south to Bucharest. They sought help at the Polish embassy, but it could do nothing.

He may have a PHD in philosophy, however I think he's misunderstanding this simplification. It has nothing to do with permutations, a permutation is equivalent to shuffling a deck of cards. Would he argue that this is also too much of a simplification? When explaining the Enigma, many people get bogged down in the details of the electrical wiring. However the essence of the enigma's operation is that each wheel position applies a specific shift to the input character. So each electrical path can be defined equivalently as some addition. The randomness of the machine, can then be explained by the random listing of numbers on the wheels. This sells the point that A. it's deterministic, and B, the rotors are pseudorandom. I simply think this is the best way to introduce the topic, it abstracts the mechanics and focuses on the mathematics Reference (i used this example as a TA in): <a rel="nofollow" class="external free" href="http://crypto.cs.mcgill.ca/~dumais/cs647/cs647.html">http://crypto.cs.mcgill.ca/~dumais/cs647/cs647.html</a> — Preceding <a href="/wiki/Wikipedia:Signatures" title="Wikipedia:Signatures">unsigned</a> comment added by <a href="/wiki/Special:Contributions/154.20.249.232" title="Special:Contributions/154.20.249.232">154.20.249.232</a> (<a href="/wiki/User_talk:154.20.249.232" title="User talk:154.20.249.232">talk</a>) <a href="https://en.wikipedia.org/wiki/Talk:Enigma_machine#c-154.20.249.232-2011-08-03T21:32:00.000Z-Why_the_odometer_analogy_works_(the_video_I_added_is_NOT_useless_and_currently_u" class="ext-discussiontools-init-timestamplink">21:32, 3 August 2011 (UTC)</a><span id="ooui-php-97" class="ext-discussiontools-init-replybutton oo-ui-widget oo-ui-widget-enabled oo-ui-buttonElement oo-ui-buttonElement-frameless oo-ui-iconElement oo-ui-labelElement oo-ui-flaggedElement-progressive oo-ui-buttonWidget" data-ooui='{"_":"OO.ui.ButtonWidget","rel":["nofollow"],"framed":false,"icon":"share","label":"Reply","flags":["progressive"],"classes":["ext-discussiontools-init-replybutton"]}'><a role="button" tabindex="0" rel="nofollow" class="oo-ui-buttonElement-button">Reply</a> NOTE: Regarding Glrx, I totally respect and read his contributions.

I've read Knuth's SemiNumerical Algorithms and we could use some middle square method. Or, why not just take a strip of pseudorandom digits, and mount them on wheels. From there we could come up with all sorts of options for then using those digits to define a shift: ie. If wheels A B C are showing, should we take Shift = A*B*C MOD 26 ? Shift = A + B + C MOD 26 ?

However, that's because of the wiring. The middle rotor doesn't randomly turn, it still clicks along as a odometer would. In this case the random digits on the rotor are performing the same job as the wiring. If we didn't have the numbers scrambled on the rotor, then yes, every press the rotors would all have to turn to some new place (which is the same as an electrical signal jumping around). The biggest problem I see is the fact that you can have A=A. However, I still think it's a useful road to explore. Especially if you want to show kids how this works and get them interested in the details of wiring.

The Enigma has a reflector. How does your analogy explain its function? The rotors are traversed right to left, reflected, and then traversed left to right. Under the addition idea, the traverse from right to left should add the numbers on the dial (shift), and the traverse from left to right should subtract them (unshift). That will make encryption and decryption work, but with shifts/addition, the rotors are now the identity operation and do nothing.</dd> <dd><a href="/wiki/User:Glrx" title="User:Glrx">Glrx</a> (<a href="/wiki/User_talk:Glrx" title="User talk:Glrx">talk</a>) <a href="https://en.wikipedia.org/wiki/Talk:Enigma_machine#c-Glrx-2011-08-05T15:28:00.000Z-154.20.249.232-2011-08-05T15:04:00.000Z" class="ext-discussiontools-init-timestamplink">15:28, 5 August 2011 (UTC)</a><span id="ooui-php-102" class="ext-discussiontools-init-replybutton oo-ui-widget oo-ui-widget-enabled oo-ui-buttonElement oo-ui-buttonElement-frameless oo-ui-iconElement oo-ui-labelElement oo-ui-flaggedElement-progressive oo-ui-buttonWidget" data-ooui='{"_":"OO.ui.ButtonWidget","rel":["nofollow"],"framed":false,"icon":"share","label":"Reply","flags":["progressive"],"classes":["ext-discussiontools-init-replybutton"]}'><a role="button" tabindex="0" rel="nofollow" class="oo-ui-buttonElement-button">Reply</a></dd></dl></dd></dl></dd></dl></dd></dl> If you read the description of the the video it explains that this animation ignores the plug-boards and the reflector - focusing on the core function which is psuedorandom shifts. Remember the addition is abstracting the entire electrical pathway, so the reflector has nothing to do with it. The reflector is simply an extra mix operation. To me the core of Enigma is: A -> (permutation) -> Shifted letter So the permutation can be explained in detail with the electrical pathways. However, there has to be an analogy to explain how this is basically a fancy odometer which outputs random shifts values. Perhaps someone could come up with a better way. Why not make it easier for everyone to understand aside from tech geeks? What would Richard Feynman do? We would agree that there is a simplification to be made here, to merely introduce the concept. THEN explain how it works. Ideally, it would be a slot machine type operation which occurs each shift. Which is what the video is trying to do. — Preceding <a href="/wiki/Wikipedia:Signatures" title="Wikipedia:Signatures">unsigned</a> comment added by <a href="/wiki/Special:Contributions/154.20.249.232" title="Special:Contributions/154.20.249.232">154.20.249.232</a> (<a href="/wiki/User_talk:154.20.249.232" title="User talk:154.20.249.232">talk</a>) <a href="https://en.wikipedia.org/wiki/Talk:Enigma_machine#c-154.20.249.232-2011-08-05T17:03:00.000Z-Why_the_odometer_analogy_works_(the_video_I_added_is_NOT_useless_and_currently_u" class="ext-discussiontools-init-timestamplink">17:03, 5 August 2011 (UTC)</a><span id="ooui-php-103" class="ext-discussiontools-init-replybutton oo-ui-widget oo-ui-widget-enabled oo-ui-buttonElement oo-ui-buttonElement-frameless oo-ui-iconElement oo-ui-labelElement oo-ui-flaggedElement-progressive oo-ui-buttonWidget" data-ooui='{"_":"OO.ui.ButtonWidget","rel":["nofollow"],"framed":false,"icon":"share","label":"Reply","flags":["progressive"],"classes":["ext-discussiontools-init-replybutton"]}'><a role="button" tabindex="0" rel="nofollow" class="oo-ui-buttonElement-button">Reply</a> </section><div class="mw-heading mw-heading2 ext-discussiontools-init-section section-heading" onclick="mfTempOpenSection(23)"><h2 id="Vast_number_of_messages" data-mw-thread-id="h-Vast_number_of_messages-2012-03-14T02:39:00.000Z">Vast number of messages</h2> <a role="button" href="/w/index.php?title=Talk:Enigma_machine&action=edit&section=23" title="Edit section: Vast number of messages" class="cdx-button cdx-button--size-large cdx-button--fake-button cdx-button--fake-button--enabled cdx-button--icon-only cdx-button--weight-quiet "> edit </a> <span id='ooui-php-208' class='ext-discussiontools-init-section-overflowMenuButton oo-ui-widget oo-ui-widget-enabled oo-ui-buttonElement oo-ui-buttonElement-frameless oo-ui-iconElement oo-ui-buttonWidget' data-ooui='{"_":"OO.ui.ButtonMenuSelectWidget","rel":["nofollow"],"framed":false,"icon":"ellipsis","data":{"itemConfigs":[{"id":"edit","data":{"id":"edit"},"icon":"edit","label":"Edit"}],"resourceLoaderModules":[]},"classes":["ext-discussiontools-init-section-overflowMenuButton"]}'><a role='button' tabindex='0' rel='nofollow' class='oo-ui-buttonElement-button'></a><div class="ext-discussiontools-init-section-bar"><div class="ext-discussiontools-init-section-metadata">Latest comment: <a href="#c-TedColes-2012-03-14T10:05:00.000Z-117.213.221.167-2012-03-14T02:39:00.000Z">12 years ago</a>2 comments2 people in discussion</div><div class="ext-discussiontools-init-section-actions"></div></div></div><section class="mf-section-23 collapsible-block" id="mf-section-23"> "Thanks to this,[6] during the war, Allied codebreakers were able to decrypt a vast number of messages that had been enciphered using the Enigma"...

The translation of "Funkschlüssel" was changed from "radio cipher" to "remote key". My sense is Funk is radio/wireless and Schlüssel is key (and possibly cipher). When used in our context, it is a radio key or radio cipher or even radio cipher machine. When referring to the device used to open modern cars, it is a remote key or a wireless key. (Yes, I know that car remote keys use encryption.) To me, the original "radio cipher" is better. The German WP article uses Rotor-Schlüsselmaschinen (literally "rotor-key machine") to denote rotor cipher machine, but my guess is that "Schlüssel" can also be used in the English sense of cipher.

It also claims criticisms of how things were at Bletchley without support. I wasn't there but the general treatment seems convincing - the mixture of informality and extreme security. Harris maybe assumes too much knowledge - Turing is very much in the background (as he was by 1943) and is hardly mentioned in the film. The major plot element - the total suppression of decryptions of the Katyn massacre - mainly hits at the secretiveness of the British, though the anti-Polish angle is bad.

I have edited his paragraph for its many lesser errors and stylistic infelicities, but the whole text is very dubious, and I have marked it as "citation needed". I cite the paragraph, below: <link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r1244412712"><blockquote class="templatequote">The Enigma D version was intercepted by the Poles on a Friday in late December 1927 at the Polish railroad customs house in Warsaw. A heavy package had arrived there, addressed to the German Embassy in Warsaw. A German representative of the "radio" company that had shipped the package, repeatedly called the customs officials, stating that the package had been shipped by mistake, must not go through customs inspection, and must be returned to Berlin immediately. His calls became increasingly frantic, until the custom officials became suspicious and notified the Polish <a href="/wiki/Biuro_Szyfr%C3%B3w" class="mw-redirect" title="Biuro Szyfrów">Cipher Bureau</a>, which was then responsible for radio-related matters. <a href="/wiki/Stefan_Mayer" title="Stefan Mayer">Stefan Mayer</a>, chief of Polish intelligence, was then informed and had his agents secretly remove the package to a location that was known not to be under Gestapo surveillance. The package was carefully opened to reveal a cipher machine virtually identical with commercial Enigma machines in use at the time. The agents correctly guessed that the Germans had modified the internal wiring; they carefully disassembled it and noted the changes. The machine was quickly reassembled and, the following Monday, shipped back to the radio company in Berlin. When Major <a href="/wiki/Gwido_Langer" title="Gwido Langer">Gwido Langer</a> took over the newly organized Cipher Bureau in 1929, he possessed the modified Enigma machine, but he did not reveal this to the newly recruited mathematics students, Marian Rejewski, Henryk Zygalski and Jerzy Róźycki. Langer correctly assumed that the Germans would make further modifications to the Enigma machine, and he only provided Rejewski with a legally purchased commercial Enigma machine. His reasoning was that he wanted his cryptologists to understand the machine's internal wiring from a purely mathematical point of view.[<a href="/wiki/Wikipedia:Citation_needed" title="Wikipedia:Citation needed">citation needed</a>]</blockquote> The three mathematicians were only recruited by the Cipher Bureau in 1932, not 1929, and by then they were no longer "students". But there are more serious errors in this paragraph, as is made clear by reading <a href="/wiki/Marian_Rejewski" title="Marian Rejewski">Marian Rejewski</a>'s Appendix D to <a href="/wiki/W%C5%82adys%C5%82aw_Kozaczuk" title="Władysław Kozaczuk">Władysław Kozaczuk</a>, Enigma: How the German Machine Cipher Was Broken, and How It Was Read by the Allies in World War Two,1984 (p. 246): <link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r1244412712"><blockquote class="templatequote">It may readily be surmised that the cipher machine [that had arrived at the Warsaw Customs Office on a "Saturday afternoon" in "late 1927 or perhaps early 1928"] was an Enigma, of the commercial model of course, since, at that time, the military model had not yet been put into use. Hence, this trivial episode was of no practical importance, though it does fix the date at which the Cipher Bureau's interest in the Enigma machine began — manifested, initially, in the acquisition by entirely legal means of one copy of the commercial model machine.</blockquote> The Cipher Bureau clearly would have had no purpose in keeping the model D's wiring a secret from Rejewski. <a href="/w/index.php?title=User:Jcolman1&action=edit&redlink=1" class="new" title="User:Jcolman1 (page does not exist)">User:Jcolman1</a>'s paragraph needs, at a minimum, to be thoroughly revised for relevance and accuracy; probably, to be dropped altogether. <a href="/wiki/User:Nihil_novi" title="User:Nihil novi">Nihil novi</a> (<a href="/wiki/User_talk:Nihil_novi" title="User talk:Nihil novi">talk</a>) <a href="https://en.wikipedia.org/wiki/Talk:Enigma_machine#c-Nihil_novi-2013-05-27T23:32:00.000Z-%22Commercial_Enigma%22" class="ext-discussiontools-init-timestamplink">23:32, 27 May 2013 (UTC)</a><span id="ooui-php-116" class="ext-discussiontools-init-replybutton oo-ui-widget oo-ui-widget-enabled oo-ui-buttonElement oo-ui-buttonElement-frameless oo-ui-iconElement oo-ui-labelElement oo-ui-flaggedElement-progressive oo-ui-buttonWidget" data-ooui='{"_":"OO.ui.ButtonWidget","rel":["nofollow"],"framed":false,"icon":"share","label":"Reply","flags":["progressive"],"classes":["ext-discussiontools-init-replybutton"]}'><a role="button" tabindex="0" rel="nofollow" class="oo-ui-buttonElement-button">Reply</a> </section><div class="mw-heading mw-heading2 ext-discussiontools-init-section section-heading" onclick="mfTempOpenSection(31)"><h2 id="Double_coding" data-mw-thread-id="h-Double_coding-2013-08-05T11:57:00.000Z">Double coding</h2> <a role="button" href="/w/index.php?title=Talk:Enigma_machine&action=edit&section=31" title="Edit section: Double coding" class="cdx-button cdx-button--size-large cdx-button--fake-button cdx-button--fake-button--enabled cdx-button--icon-only cdx-button--weight-quiet "> edit </a> <span id='ooui-php-216' class='ext-discussiontools-init-section-overflowMenuButton oo-ui-widget oo-ui-widget-enabled oo-ui-buttonElement oo-ui-buttonElement-frameless oo-ui-iconElement oo-ui-buttonWidget' data-ooui='{"_":"OO.ui.ButtonMenuSelectWidget","rel":["nofollow"],"framed":false,"icon":"ellipsis","data":{"itemConfigs":[{"id":"edit","data":{"id":"edit"},"icon":"edit","label":"Edit"}],"resourceLoaderModules":[]},"classes":["ext-discussiontools-init-section-overflowMenuButton"]}'><a role='button' tabindex='0' rel='nofollow' class='oo-ui-buttonElement-button'></a><div class="ext-discussiontools-init-section-bar"><div class="ext-discussiontools-init-section-metadata">Latest comment: <a href="#c-176.25.202.193-2015-02-15T17:40:00.000Z-TreebeardTheEnt-2014-12-27T20:24:00.000Z">9 years ago</a>20 comments11 people in discussion</div><div class="ext-discussiontools-init-section-actions"></div></div></div><section class="mf-section-31 collapsible-block" id="mf-section-31"> I recently visited the U-Boat U534 on display at Birkenhead (<a class="external free" href="https://en.wikipedia.org/wiki/German_submarine_U-534">http://en.wikipedia.org/wiki/German_submarine_U-534</a>).

Unintelligible plaintext might as well serve as 'not cracked.' or be viewed as 'chaff' In addition, B) deciphering was a time consuming activity not assisted by computation so anything that increased the time to crack to plaintext was viewed as helpful for keeping secrets. For instance, if I encrypt the plaintext phrase "hello there" once into the cyphertext "3tdrw234" and then, treating that as plaintext, encrypt it again, gaining the new cyphertext "bl0o32sdd e3a" (all examples made up for illustrative purposes only) anybody attempting to decypher "bl0o32sdd e3a" would, if done correctly get "3tdrw234". The cryptanalyst would have a decision: trust the math and assume double encryption and repeat the time consuming process or believe that a mistake was made and repeat the original cryptanalysis. Before computers the task of going from "bl0o32sdd e3a" directly to "hello there" in a double encryption was neither easy nor quick, if at all possible. <a href="/wiki/User:TreebeardTheEnt" class="mw-redirect" title="User:TreebeardTheEnt">TreebeardTheEnt</a> (<a href="/wiki/User_talk:TreebeardTheEnt" class="mw-redirect" title="User talk:TreebeardTheEnt">talk</a>) <a href="https://en.wikipedia.org/wiki/Talk:Enigma_machine#c-TreebeardTheEnt-2014-12-27T20:24:00.000Z-194.176.105.138-2014-07-07T13:32:00.000Z" class="ext-discussiontools-init-timestamplink">20:24, 27 December 2014 (UTC)</a><span id="ooui-php-132" class="ext-discussiontools-init-replybutton oo-ui-widget oo-ui-widget-enabled oo-ui-buttonElement oo-ui-buttonElement-frameless oo-ui-iconElement oo-ui-labelElement oo-ui-flaggedElement-progressive oo-ui-buttonWidget" data-ooui='{"_":"OO.ui.ButtonWidget","rel":["nofollow"],"framed":false,"icon":"share","label":"Reply","flags":["progressive"],"classes":["ext-discussiontools-init-replybutton"]}'><a role="button" tabindex="0" rel="nofollow" class="oo-ui-buttonElement-button">Reply</a></dd></dl></dd></dl></dd></dl> <dl><dd><dl><dd><dl><dd><dl><dd>You seem to have ignored the argument that a double encryption only requires a single decryption.

In this case double encryption takes twice the work and provides no more security than a single encryption step! Even if the cipher is not a cryptographic group, there is something called a “meet in the middle” attack that makes the sequence of encryption operations no more secure against a brute-force attack than just encrypting it once. Chaining multiple encryption steps is not a great way to improve on security. <a href="/wiki/Special:Contributions/194.176.105.136" title="Special:Contributions/194.176.105.136">194.176.105.136</a> (<a href="/wiki/User_talk:194.176.105.136" title="User talk:194.176.105.136">talk</a>) <a href="https://en.wikipedia.org/wiki/Talk:Enigma_machine#c-194.176.105.136-2014-07-29T12:17:00.000Z-Double_coding" class="ext-discussiontools-init-timestamplink">12:17, 29 July 2014 (UTC)</a><span id="ooui-php-134" class="ext-discussiontools-init-replybutton oo-ui-widget oo-ui-widget-enabled oo-ui-buttonElement oo-ui-buttonElement-frameless oo-ui-iconElement oo-ui-labelElement oo-ui-flaggedElement-progressive oo-ui-buttonWidget" data-ooui='{"_":"OO.ui.ButtonWidget","rel":["nofollow"],"framed":false,"icon":"share","label":"Reply","flags":["progressive"],"classes":["ext-discussiontools-init-replybutton"]}'><a role="button" tabindex="0" rel="nofollow" class="oo-ui-buttonElement-button">Reply</a> <dl><dd>This is true only for definitions of 'brute force' that includes assistance from a combination of advanced mathematics and programmable computers, both of which were invented in response to a need well after the implementation and use of advanced encryption techniques like chaining multiple encryption steps.

In the year 1918, the year of its invention by Arthur Scherbius, there existed no Enigma machines at all. And the plugboard (Steckerbrett) was introduced in 1928 by the German Army (Reichswehr). The presented Enigma machine of the museum in Milano is a typical 3-wheel-plugboard model “Enigma I” as used by the German Armed Forces (Wehrmacht) during the late 1930s and during the war. So the date should read “ca. 1940”.

In the first place, this article is about a German machine, not Polish success in defeating it. So let's cut down the Polish content from the lede, as well as what appears to be a reaction against it in the content. Simply put, the British by their own account said they never would have achieved what they did against Enigma without having been given the insight by their Polish allies "in the nick of time" at the start of the War - not much more needs to be said about it than that.

There is (in the literature) a bit of a battle for recognition between the Poles and the British. During the decade leading up to WWII, the Poles were more successful than the British because they were attacking with mathematical methods, and they had some help such as "Asche" documents. The British learned about the mechanical means, the importance of the decrypts from the Enigma, and about the mathematical approach--all from the Poles. But Alan Turing and Gordon Welchman took this significantly further. The Polish methods were not adaptable--while, for example, the Turing-Welchman 'Bombe' machine could be reconfigured. Throughout the war, many basic ideas from the Poles continued to be used to cut down the amount of work, most notably the 'Zygalski sheets' in various forms.</dd> <dd>But the British contribution, especially the Welchman "diagonal board" methods allowed for deductions from the mechanical means that were much more effective than the original Polish methods--when the volume of traffic to be decrypted reached that level of productivity. Having 100's of the original Polish 'Bomba' machines (without regard to cost) would not have solved Enigma traffic later when the German procedures changed. One major problem is that the Polish Cypher Bureau personnell were not allowed to work on their project after they arrived in GB, and were essentially shuttled to less important jobs.</dd> <dd>Then there is a tenstion between the British and Americans over first computer developments (Colossus related and unrelated to Enigma decryption), but these tensions make for different books that declare contradictory stories of the importance of the contributions of the parties. As I see it, the facts are that without the Polish contribution, Bletchley Park would have been many months behind and might well never have made the progress they did. Then without the new insights of Turing and Welchman and others, and of course the later production of equipment ('Bombe's etc.) the ability to decrypt Enigma trafic would have faltered as well. By the later years, 4-rotor Naval enigma decryption was carried out in the US on 4-rotor based US Naval Boombe equipment (Dayton codebreakers), with job requests being transmitted over undersea cable to the US from Bletchley Park, because the British could not keep up with the production of their Bombe equipement needed for all the traffic.</dd> <dd>Each of several groups thus made completely irreplaceable contributions.</dd> <dd>I do agree that the section "Breaking Enigma" has an imbalance. The reason is that Enigma wasn't "broken" just once, but many times and in different ways--both for different variations of the machine, but also different code nets had different procedures that were exploited in different ways. One single "breaking" event (the initial Polish effort) is not a sufficient decription.</dd> <dd>At the risk of making that section too long, I would expand the end to include further "breaking" exploits and explain it had to be done repeatedly. Then in essence shorten the Polish introductory section by using fewer words and shortening the exploits a bit. NOT by removing that or minimizing that.
