AWS details an X.509 PKI architecture for securing AI agent identity
AWS published a reference architecture using Keyfactor EJBCA and AWS services to secure AI agent identity via X.509 PKI.
Summary
AWS published a reference architecture to secure AI agent identity using X.509 public key infrastructure with Keyfactor EJBCA and AWS services. The architecture addresses authentication gaps using signed request envelopes, user-signed delegation assertions, audience-scoped tokens, and real-time OCSP revocation checking.
What changed
- Uses X.509 public key infrastructure to establish cryptographic identity for AI agents
- Implements signed request envelopes for proof-of-possession on every agent call
- Applies user-signed delegation assertions to authorize agents without sharing credentials
- Enforces real-time OCSP revocation checking to immediately propagate credential changes
Availability
Available now“Complete source code for all examples is available in the accompanying GitHub repository.”
Founder takeaway
Review the published GitHub reference architecture if you need to implement cryptographic identity and security controls for multi-agent AI systems.
