A single agent has one identity and one perimeter; a mesh of agents that call, delegate to, and depend on one another has neither. This series builds trust and security models for multi-agent systems from the ground up: why agent meshes break the perimeter and single-identity assumptions that security was built on, how to reason about trust with capability-based, reputation-based, and zero-trust models specialized to meshes, how trust propagates through delegation and where transitive trust turns into confused-deputy attacks at scale, how agents make verifiable claims to one another through attestation and signed provenance, and how it all assembles into a reference architecture of trust brokers, policy meshes, and failure containment. Grounded in NIST SP 800-207 Zero Trust, the NIST AI RMF, the OWASP Agentic Security Initiative and LLM Top 10, MITRE ATLAS, the SPIFFE workload-identity specification, the OAuth 2.0 Token Exchange RFC, object-capability security, and the peer-reviewed literature on reputation systems and zero-knowledge proofs.
