Abstract:

   This document defines the OpenA2A Agent Identity Protocol (OpenA2A
   AIP), an open standard for creating, managing, and verifying
   cryptographic identities for AI agents.  As AI agents proliferate
   across browsers, cloud platforms, and enterprise environments,
   systems need a standardized answer to the question of which agent is
   present, what it is permitted to do, and whether it should be
   trusted.

   OpenA2A AIP is distinguished by five elements that it places at the
   center of the design: a multi-factor behavioral trust score that is
   computed from independently verifiable signals; a portable signed
   credential, the Agent Trust eXtension, carrying a hybrid Ed25519 and
   ML-DSA-65 signature for post-quantum readiness; an append-only, RFC
   9162-style Merkle transparency log for identity and credential
   issuance; agent identifiers expressed as W3C Decentralized
   Identifiers under the did:opena2a method; and a structured capability
   vocabulary with reserved namespaces.  On top of these, the protocol
   specifies challenge-response verification, behavioral governance
   policies, a lifecycle model, and an append-only audit log.

   The qualifier "OpenA2A AIP" is used throughout this document because
   the abbreviation "AIP" is shared by other Internet-Drafts.  OpenA2A
   AIP is framed as complementary to agent communication protocols such
   as A2A and the Model Context Protocol, and to identity and credential
   standards such as OpenID Connect, WebAuthn, and the W3C Verifiable
   Credentials Data Model.
