Depending on the level of security to be implemented, these are stated in the European regulation (EU) 2015/1502 (Minimum requirements and technical specifications on procedures for security levels of electronic identification means). Currently, requirements for identity wallets, digital credentials, and self-sovereign identities (SSI) are under active development.</p> <p>There still are many challenges for all stakeholders that prevent secure digital identities from being used widely.</p> <p>Research in this area conducted by the Secure Systems Engineering department focuses not only on the security of identity solutions, but also on interoperability, privacy, and usability.

ML models are trained to make generalized predictions on unknown data based on their training data. In recent years, there has been a growing understanding that, in many cases, even though a model supposedly contains only an abstraction of its training data, it by no means sufficiently protects the privacy of individuals whose data was used in training said model.</p> <p>It is possible to draw conclusions about the training data from the parameters of a model (e.g., via so-called property inference or model inversion attacks). Protection against such attacks can be provided by mechanisms such as Differential Privacy (DP), which is a mathematical framework that allows meaningful analyses to be performed on a group of individuals without violating the privacy of any single individual. This purpose is achieved by adding mathematical noise during a given analysis. Most commonly, the noise is added in various forms during model training, thereby allowing the privacy of individuals in the training dataset to be protected.</p></div> </div> </div> </article> </div> </div> </div> </div> <div data-emptytext="tabview_tabcontent_hint" class="accordion-item tab-item section"><h2 class="item-heading fragment" id="tabview_tab_152497787-heading"> <a class="item-title item-trigger collapsed" data-toggle="collapse" href="#152497789" aria-expanded="false" aria-controls="tabview_tab_152497787-content" title="Usable Security and Privacy"> Usable Security and Privacy</a></h2> <div class="item-body collapse" id="152497789" aria-labelledby="tabview_tab_152497787-heading"> <div class="tabPar parsys"><div class="fhg-content-article fhg-grid section"><article> <div class="row"> <div class="fhg-grid-item fhg-grid-3-2-1"> <div class="fhg-content fhg-richtext"> <p>Often, the requirements, knowledge and skills of the target audience are not considered at the beginning, but rather at the end of the design phase. Usually, the security goals ("What needs to be protected?") and the security model ("How should it be protected?") are defined first. However, the selected security model has a significant impact on possible user interactions, usually resulting in significant weaknesses regarding usability.</p> <p>An important requirement for usable systems is allowing users to reach their goal while keeping interactions to a minimum. From the perspective of usable security and privacy, this is in most cases is neither possible nor meaningful. Legally binding processes, such as signing a contract or giving consent, require active involvement of users. Interaction should be minimized only to a point where trust in the system does not diminish, and users are not left uncertain about the state of the system.</p> <p>Our research is focused on the development of methods and tools for assessing the usability of- and trust in secure systems and privacy measures, as well as on the development of models for easy and error-free use of such systems. </p></div> </div> </div> </article> </div> </div> </div> </div> </div> </div> </div> <div data-emptytext="teaser_overview_parsys_hint" class="teaser section"><div class="sep sectionseparator"><script data-scf-json="true" type='application/json' id='/en/fields-of-expertise/SSE/jcr:content/contentPar/teaser_overview_827940098/sep'>{"id":"/en/fields-of-expertise/SSE/jcr:content/contentPar/teaser_overview_827940098/sep","resourceType":"fraunhofer/components/sectionseparator","url":"/en/fields-of-expertise/SSE/_jcr_content/contentPar/teaser_overview_827940098/sep.social.json","friendlyUrl":"/en/fields-of-expertise/SSE.html"}</script><div class="fhg-section-separator"></div> </div> <div class="fhg-grid teaser-layout fhg-grid-4-columns"> <div class="fhg-grid-item teaser-layout__title "> <h2 class="teaser-layout__title-headline fragment" id="Selected-Projects">Selected Projects</h2> </div> <div class="fhg-grid teaser-layout--masonry js-teaser-layout--masonry" data-config-masonry='{"horizontalOrder":false}'> <div class="fhg-grid-column-sizer"></div> <div class="teaserPar parsys"><div data-emptytext="linklist_add_items" class="teaser__item section"><div class="fhg-grid-item teaser-default teaser-default--size-1x2 teaser-default--variant- teaser-default--color-white teaser-default--has-image js-teaser-ellipsis"> <div class="teaser-default__content"> <a href="https://www.aisec.fraunhofer.de/en/about-us/Competence-Center-PQC.html" class="teaser-default__image teaser-default__image--linked teaser-default__image--small small" style="background-image: url('/en/fields-of-expertise/SSE/jcr:content/contentPar/teaser_overview_827940098/teaserPar/teaser_copy/image.img.2col.large.jpg/1721748071280/Header-Kompetenzzentrum-Post-Quanten-Kryptografie-2.jpg');background-position: 50% 50%" target="_blank"> </a><div class="teaser-default__text"> <div class="teaser-default__text-caption js-teaser-default__text-caption"> <h3 class="teaser-default__text-headline">Competence Center for Post-Quantum Cryptography</h3> <div class="teaser-default__text-richtext"><p>Fraunhofer AISEC is pooling its expertise in the future technology of post-quantum cryptography (PQC) via the Competence Center for Post-Quantum Cryptography.
