                   The Entity Attestation Token (EAT)
                         draft-ietf-rats-eat-00

Abstract

   An attestation format based on concise binary object representation
   (CBOR) is proposed that is suitable for inclusion in a CBOR Web Token
   (CWT), know as the Entity Attestation Token (EAT).  The associated
   data can be used by a relying party to assess the security state of a
   remote device or module.
