ARIA Protocol v1.0 — Public Launch
April 1, 2026 · TrustLayer Foundation A.C.
The first public release of the ARIA Protocol specification — the open protocol for AI agent identity.
What's included
- Specification: Complete protocol architecture — trust levels (L0–L3), AID structure, DNS anchoring, delegation, revocation
- Agent Trust Protocol (ATP): Three-phase handshake for agent admission — declare, evaluate, admit
- JSON Schemas: Machine-readable schemas for AID, ATP policy, and intent declarations
- Examples: Sample AID document, ATP DNS policy, and TypeScript verification code
- Governance: CONTRIBUTING guide, security policy, issue templates
Standards alignment
- NIST SP 800-63-4 (IAL 1–3)
- FIPS 204 (ML-DSA-65) + RFC 8032 (Ed25519)
- W3C DID Core / W3C VC Data Model 2.0
- CA/B Forum SC-081v3
- StatusList 2021
Cryptography
Composite signatures: ML-DSA-65 (post-quantum, FIPS 204) + Ed25519 (classical, RFC 8032). Both must verify. Not a migration plan — the launch configuration.
