agent-identity

Agent identity management, trust scoring, and certificate management

Part of the AumOS open-source agent infrastructure portfolio.

Features

• DID-based identity registry assigns each agent a decentralized identifier with a verifiable credential; IdentityRegistry provides lookup and resolution
• TrustScorer computes a composite trust score from three weighted dimensions — competence (40%), reliability (35%), and integrity (25%) — updated via outcome observations (success, failure, violation)
• Certificate management with an agent CA, certificate issuance, revocation lists, verification, and automatic rotation on configurable expiry schedules
• Behavioral fingerprinting builds a baseline profile of an agent's interaction patterns and raises alerts when its behavior deviates — useful for detecting compromised or impersonated agents
• Delegation token chain allows an agent to delegate a subset of its permissions to a sub-agent, with revocation propagating down the full chain
• RBAC middleware enforces role-based access at call boundaries; audit middleware records every identity-check decision for compliance review
• Trust history log tracks score trajectories over time so administrators can review how an agent's trust evolved before granting elevated permissions
