Abstract:

   This document defines a trust model for agent-to-agent (A2A)
   interactions in multi-agent AI systems.  It specifies how agents
   obtain verifiable identities via CA-signed templates, how spawn
   chains are cryptographically established and validated, how dynamic
   policies are governed under a dual-signature model, and how cross-
   organizational agent interactions are explicitly authorized.  The
   model applies existing PKI primitives (X.509, CRL, CSR) and
   established identity patterns (OAuth 2.0, On-Behalf-Of) to the
   problem of agent provenance.  This document does not address agent-
   to-resource access control, human-in-the-loop orchestration, or agent
   behavior, as those concerns belong to the resource enforcement layer
   and the orchestration layer respectively.
