DMTF’s Security Protocols and Data Models Working Group recently released the Security Protocol and Data Model (SPDM) to Storage Binding Specification 1.0 (DSP0286), which defines the format of SPDM messages over storage protocols. This specification binds SPDM messages (DSP0274) and SPDM Secured Messages (DSP0277) to storage protocols. This binding specification enables the extension of the capabilities defined in the Security Protocol and Data Model (SPDM) Specification to storage devices. Further, this binding specification enables the use of intermediate devices, such as a host bus adapter, between the Requester and the storage device.

Key highlights from the Specification include:

• Supports all released versions of SPDM (DSP0274) and SPDM Secured Messages (DSP0277)
• Define a binding for SPDM messages over SAS (SCSI), SATA (ATA), and NVMe (PCIe and Fabrics)
  • The binding applies directly to SPDM and does not include MCTP
  • Both SPDM messages and SPDM Secured Messages are supported
• This specification serves the roles of both DSP0275 and DSP0276

This specification – developed by DMTF’s SPDM Working Group – continues 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.
