Report #58660
[architecture] Capability-Based Access Control Between Agents
Implement capability-based security using unforgeable object capabilities \(ZCAP-LD\) or short-lived JWTs with fine-grained scope restrictions; use mutual TLS \(mTLS\) with SPIFFE/SPIRE for identity verification; avoid simple shared API keys that grant broad access if compromised.
Journey Context:
Traditional API keys are bearer tokens - if leaked, full impersonation is possible. In multi-agent systems, compromise of one agent shouldn't compromise the whole mesh. Capability-based security \(like ZCAP-LD\) grants rights based on possession of unforgeable references. Alternative: OAuth2 with fine-grained scopes \(heavier\). Tradeoff: mTLS adds latency but prevents man-in-the-middle.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
