Abstract

   This document defines an interaction model for a basic remote
   attestation procedure.  Additionally, the required information
   elements are illustrated.

1.  Introduction

   Remote attestation procedures (RATS) are a combination of activities,
   in which a Verifier creates assertions about claims of integrity and
   about the characteristics of other system entities by the appraisal
   of corresponding signed claim sets (evidence).  In this document, a
   reference interaction model for a generic challenge-response-based
   remote attestation procedure is provided.  The minimum set of
   components, roles and information elements that have to be conveyed
   between Verifier and Attestor are defined as a standard reference to
   derive more complex RATS from.

1.1.  Requirements notation

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and
   "OPTIONAL" in this document are to be interpreted as described in RFC
   2119, BCP 14 [RFC2119].

2.  Disambiguation

   The term "Remote Attestation" is a common expression and often
   associated with certain properties.  The term "Remote" in this
   context does not necessarily refer to a remote system entity in the
   scope of network topologies or the Internet.  It rather refers to a
