Cryptographic Attestation
Using cryptographic signatures to prove agent identity, configuration, or output authenticity, enabling tamper-evident verification.
What is Cryptographic Attestation?
Cryptographic attestation employs digital signatures, hash functions, and public key infrastructure to create verifiable proofs. Agents sign outputs with private keys, allowing anyone to verify authenticity using public keys. Configuration attestation proves an agent is running specified code without modification. This prevents impersonation and ensures integrity.
Attestation mechanisms include code signing, remote attestation for execution environments, and signed audit logs. Trust anchors (certificate authorities, hardware security modules) provide root of trust for verification chains.
Example
An agent digitally signs each transaction recommendation with its private key, allowing recipients to verify the output came from the authentic agent and wasn't modified in transit, with signatures recorded in immutable audit trails.
How Signet addresses this
Signet uses cryptographic attestation to bind agent identities to SIDs, preventing impersonation. Signed audit trail entries provide tamper-evident records of agent actions for compliance and dispute resolution.
