A2AShield: 双向后量子 mTLS 通信、W3C DID 硬件证明与密码学可信委托

A2AShield 为自主 AI 智能体提供零信任密码通信网格、双向后量子 TLS (mTLS) 及可密码学验证的授权委托链，赋能多智能体集群在消除身份伪造、提示注入与量子拦截风险的前提下执行复杂协商与业务流。

A2AShield Autonomous Agent Security Pipeline & Delegation Architecture

Mutual agent attestation, cryptographically bound task delegation, and quantum mTLS mesh

Central System: Agent Security Mesh - A2A Cryptographic Gateway

Cryptographic Nodes

  • Agent Identity Issuer
  • Delegation Chain Verifier
  • Hybrid mTLS Tunnel
  • Tool Execution Sandbox
  • Forensic Agent Auditor

Architectural Layers & Protocols

  • Agent Cryptographic Identity Plane (Decentralized Identifiers (DID) / SPIFFE for Agents): Assigning each autonomous AI agent a unique, non-spoofable post-quantum cryptographic identity.
  • Mutual Post-Quantum Transport (Mutual TLS 1.3 with Hybrid ML-KEM/ML-DSA): Encrypting and mutually authenticating all inter-agent messages, prompts, and tool results.
  • Cryptographic Delegation Chains (Macaroons / Biscuits with Post-Quantum Signatures): Encoding precise task delegation, spending allowances, and operational scopes from human to agent.
  • Anti-Prompt-Injection Boundary (Structured Content Enclaves & Attested Tools): Isolating untrusted user inputs from high-privilege agent execution tools via cryptographic gates.

Key Metrics: < 3 ms (Agent-to-Agent Handshake) | 100% (Delegation Chain Verification) | Zero-Trust (Mutual Authentication Standard) | Immutable (Reasoning & Action Audit Logs)
