AI overview

AWS and Keyfactor demonstrated a reference architecture that uses X.509 public key infrastructure, Keyfactor EJBCA, and AWS services to secure AI agent communications. The walkthrough covers user login, communication between agents, and access to tools through the Model Context Protocol (MCP). The architecture combines signed request envelopes, user-signed delegation assertions, audience-scoped tokens, and real-time Online Certificate Status Protocol (OCSP) checks. The demonstration uses Amazon Bedrock, the AWS Strands Agents SDK, and FastMCP, and includes replay prevention and credential revocation at logout.
