In network protocol exchanges, it is often the case that one entity (a Relying Party) requires evidence about a remote peer to assess the peer’s trustworthiness, and a way to appraise such evidence. The evidence is typically a set of claims about its software and hardware platform. This document describes an architecture for such remote attestation procedures (RATS).
