Multi-Agent Systems and Agent-to-Agent Trust

Multi-agent security depends on the boundaries between cooperating workers. Authenticate peers, establish the user or service-owned task grant, authorize each resource and recipient, and constrain aggregate work. Structured handoffs and provenance support these checks but do not establish truth or permission. A2A provides interoperability; issuers and applications still define the authority and lifecycle of each operation.
