Agent Name Service (ANS) enables offline, sub-millisecond verification of agent identity before sensitive data is transmitted, using cryptographic methods separate from authorization frameworks like OAuth 2.0. Born from OWASP and IETF standards, ANS provides versioned identities, transparency logs, and short-lived status tokens for efficient agent management in autonomous AI systems. The service allows clients to verify server identity through three checks before sharing credentials, addressing security challenges in agent-to-agent communication.
