Cryptographic Identity Rotation
Securing the lifespan of agent identity.
Problem
Agents operating autonomously for months hold highly privileged API keys. If a key is leaked or compromised, the entire organizational boundary is at risk. Manual revocation is too slow for machine-speed trading or orchestration.
Approach
Implement short-lived cryptographic identities tied to the organism's execution lifecycle. The Guardian node dynamically negotiates temporary session tokens (e.g., via AWS STS or equivalent mutual TLS) that expire after a set duration. If an agent goes rogue, its credentials naturally expire within seconds/minutes.
Invariants
- No static, non-expiring credentials allowed in the
PolicyEnginescope. - Max token Time-To-Live (TTL) is 15 minutes.
