9. Authentication

ACP uses the same HMAC-SHA256 authentication as AIGP (RFC-010 4).

Every context fetch is authenticated:

  • Provider validates the requester’s HMAC signature
  • Provider checks the requester’s app_id is registered with governance-server
  • Provider checks the requester is authorized to fetch the requested context_type
