A2AShield: 상호 양자 내성 mTLS, W3C DID 하드웨어 증명 및 암호학적 권한 위임

A2AShield는 자율형 AI 에이전트를 위한 제로 트러스트 암호화 통신 패브릭, 양자 내성 상호 TLS(mTLS) 및 검증 가능한 암호학적 위임 체인을 제공하여, 사칭, 인젝션 및 양자 도청 위험 없이 다중 에이전트 군집이 복잡한 워크플로를 안전하게 실행하도록 지원합니다.

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)
