Report #41144
[architecture] Agent impersonation without cryptographic verification of origin
Sign agent outputs using JSON Web Signatures \(JWS\); downstream agents verify signatures against a trusted key registry before processing, ensuring non-repudiation and preventing spoofed messages.
Journey Context:
In a distributed system, any service can claim to be 'Agent A'. Without crypto, compromised middleware can inject fake outputs. The fix treats agents as security principals: Ed25519 or RSA keys per agent, JWS for compact signing, and verification at the ingress of every downstream agent. This mirrors mTLS but for message-level content.
