Title: OpenA2A Agent Identity Protocol (AIP)

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.
