DMTF’s SPDM Code Task Force announces its latest open source release of libspdm, version 2.2.0, which is conformant with DSP0274 1.0.1, 1.1.2 and 1.2.1, and is now available for download.  It also contains support for DSP0277, 276, and 275.  You can find all of this in the group’s readme here. In addition, details such as the SPDM supported commands, cryptographic algorithm support, design, threat model, and users guide can also be found in the readme in the repository.
 
Protocols defined by SPDM can be used for a wide range of security functionalities including authentication of hardware/firmware identities, delivering measurements, performing attestation, and establishing session keys for secure communication channels. 
 
In addition to the core library, libspdm enables spdm-emu, which contains a full SPDM Requester and Responder; spdm-dump, which can parse SPDM messages; and the SPDM Responder Validator, which is still under development but can be used to test an SPDM Responder implementation for its conformance to the SPDM specification.
