Continuous Agent Verification: Building Trustworthy Multi-Agent Networks

As autonomous agents become prevalent in production systems, secure agent-to-agent communication has shifted from optional to essential. One-time handshake authentication proves insufficient for long-running conversations, as key compromise, agent substitution, and behavioral drift occur after initial checks. This project demonstrates why continuous cryptographic verification on every message—through Ed25519 signatures and persistent registry validation—is critical to maintain active trust rather than assumed security in multi-agent infrastructure.
