3 Scope

3.1 Security Protocol and Data Model (SPDM) Specification (DSP0274) DSP0274 describes how to use messages, data objects, and sequences to exchange messages between two devices over a variety of transports and physical media. DSP0274 contains the message exchanges, sequence diagrams, message formats, and other relevant semantics for such message exchanges, including authentication of hardware identities and firmware measurements. Other specifications define the mapping of these messages to different transports and physical media. DSP0274 provides information to enable security policy enforcement but does not specify individual policy decisions.

3.2 SPDM over MCTP Binding Specification (DSP0275) DSP0275 defines the format of Security Protocol and Data Model (SPDM) over MCTP messages. DSP0275 describes both SPDM over MCTP binding and the common format for SPDM over MCTP messages.

3.3 Secured Messages using SPDM over MCTP Binding Specification (DSP0276) DSP0276 binds Secured Messages using SPDM to MCTP transport and further defines the transport specific details as outlined in Secured Messages using SPDM Specification (DSP0277). DSP0276 1.2.0 (this version) binds to version 1.2.0 and all 1.2 errata versions of DSP0277.
