DMTF’s Security Protocols and Data Models Working Group recently released the Security Protocol and Data Model (SPDM) to Storage Binding Specification Work-in-Progress (DSP0286 1.0.0WIP90), which defines the format of SPDM messages over storage protocols. This specification will bind SPDM messages (DSP0274) and SPDM Secured Messages (DSP0277) to storage protocols.

Key highlights from the WIP include:

• Enable a binding for SPDM messages over SAS (SCSI), SATA (ATA), and NVMe
  • The new standard will be DSP0286
• The binding is for SPDM, not for generic MCTP
  • The Security Protocol ID that is assigned for SPDM is 0xE8
• Both SPDM messages and SPDM Secured Messages are supported
  • This specification serves the roles of both DSP0275 and DSP0276
  • A primary goal is to support new SPDM revisions without major changes to the binding specification
• Expected release Q4 2024
  • Work in progress version is available now (https://www.dmtf.org/sites/default/files/standards/documents/DSP0286_1.0.0WIP90.pdf ) 

These specifications – developed by DMTF’s SPDM Working Group – continue to incorporate the input of the organization’s Alliance Partners. To submit feedback, please use the DMTF Feedback Portal at https://www.dmtf.org/standards/feedback.
