Attested Intelligence Technology

End-to-end cryptographic attestation protocol for AI systems, policy artifacts, and autonomous agents. Verify offline without network trust.

End-to-End Flow

1

Subject

AI model, agent, or software artifact to be attested

2

Attestation

Cryptographic binding of subject properties and metadata

3

Salted Commitment

BLAKE2b-256 hash with optional salt for privacy

4

Sealed Artifact

Ed25519-signed, immutable attestation package

5

Sentinel Enforcement

Runtime policy monitoring and receipt generation

6

Continuity Chain

Hash-linked receipt sequence for tamper evidence

Cryptography Surface

HashingBLAKE2b-256

Fast, secure hashing for artifact fingerprinting. 256-bit output provides collision resistance.

SignaturesEd25519

Modern elliptic curve signatures. Fast verification, small keys, strong security.

TimestampsRFC 3161

Optional trusted timestamp authority integration for authoritative time binding.

SchemaJSON Schema 2020-12

Standard schema format for attestation artifact validation.

Artifacts

The protocol produces verifiable artifacts that can be inspected, validated, and used for compliance.
