DMTF’s Security Protocols and Data Models (SPDM) Working group is responsible for the SPDM standard. This standard enables authentication, attestation and key exchange to assist in providing infrastructure security enablement. Other messages that extend functionality of SPDM as well as the development of other standards that enable and enhance infrastructure security are also developed by the SPDM WG.</p><p>The <a href="https://www.dmtf.org/dsp/DSP0274">SPDM Specification (DSP0274)</a> is designed to be enabled over a variety of media and thus can be referenced by other standards organizations and developers. SPDM incorporates the input of these external organizations, through the DMTF Alliance Partner process, to help align component authentication, confidentiality, and integrity objects across the industry.</p><p>The Security Protocol and Data Model over MCTP Binding Specification (DSP0275) & Secured Messages using SPDM over MCTP Binding Specification (DSP0276) fall under the purview of <a href="https://www.dmtf.org/standards/pmci">DMTF’s PMCI WG</a>. They are published on this page as a courtesy as the PMCI WG and SPDM WG work cooperatively to maintain the specifications.</p><h3>Get Involved</h3><ul><li>Technical work on SPDM standards takes place in the Security Protocols & and Data Models Working Group.</li><li>DMTF members are encouraged to contribute and access the work of the SPDM Working Group via its <a href="https://members.dmtf.org/wg/spdm/workgroup" moz-do-not-send="true">private, members-only workspace</a>. Non-members, learn more and <a href="http://dmtf.org/join">join DMTF</a> to participate. </li><li>DMTF <a href="https://www.dmtf.org/standards/feedback">welcomes feedback</a> on our standards, but requires that individuals submitting comments first agree to our DMTF Feedback Policy.</li></ul><p> </p><h3>Upcoming Workgroup Deliverables</h3><table border="1" cellpadding="2" cellspacing="0"
