The IETF Remote ATtestation procedureS architecture (RFC 9334): the shared vocabulary of attesters, verifiers, relying parties, evidence and reference values.
RATS names the roles: Attester, Verifier, Relying Party, Endorser and Reference Value Provider. It describes two main patterns. In the passport model, the attester carries a verifier's result to the relying party. In the background-check model, the relying party asks the verifier itself.
Related IETF work defines formats such as the Entity Attestation Token (EAT) for claims and CoRIM for reference values and endorsements.
Example. A confidential virtual machine is the attester. A cloud attestation service is the verifier. The key server that releases a secret is the relying party.
