A2AShield: TLS Mutuel Post-Quantique, Attestation DID W3C et Délégation Cryptographique

A2AShield fournit des tissus de communication cryptographique zero-trust, un TLS mutuel post-quantique (mTLS) et des chaînes de délégation vérifiables pour les agents IA autonomes, permettant aux essaims multi-agents de négocier et d'exécuter des flux complexes sans risque d'usurpation ou d'interception quantique.

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)
