     Reference Interaction Models for Remote Attestation Procedures
            draft-ietf-rats-reference-interaction-models-01

Abstract

   This document describes interaction models for remote attestation
   procedures (RATS).  Three conveying mechanisms - Challenge/Response,
   Uni-Directional, and Streaming Remote Attestation - are illustrated
   and defined.  Analogously, a general overview about the information
   elements typically used by corresponding conveyance protocols are
   highlighted.  Privacy preserving conveyance of Evidence via Direct
   Anonymous Attestation is elaborated on in the context of the
   Attester, Endorser, and Verifier role.
