openprot-spdm-responder

SPDM responder (server) implementation for OpenPRoT.

Overview

This crate provides the SPDM responder role, which handles attestation requests from SPDM requesters. The responder processes requests and provides:

• Version and capability negotiation
• Certificate chain provisioning
• Device measurements
• Challenge-response attestation
• CSR generation and certificate updates

Status

This crate is in early development. Basic infrastructure is in place, but SPDM protocol operations are not yet implemented.

Dependencies

• spdm-lib — SPDM protocol library from 9elements
• heapless — no_std collections

Future Work

• Implement SPDM 1.2+ response handlers
• Add GET_VERSION, GET_CAPABILITIES handlers
• Implement CHALLENGE response with signature
• Add GET_MEASUREMENTS handler
• Integrate with certificate storage
• Integrate with MCTP transport layer
• Add crypto service integration for signing operations
