 Trustworthiness Vectors for the Software Updates of Internet of Things
                         (SUIT) Workflow Model
                   draft-birkholz-rats-suit-claims-00

Abstract

   The IETF Remote Attestation Procedures (RATS) architecture defines
   Conceptual Messages as input and output of the appraisal process that
   assesses the trustworthiness of remote peers: Evidence and
   Attestation Results.  Based on the Trustworthiness Vectors defined in
   Trusted Path Routing, this document defines a core set of Claims to
   be used in Evidence and Attestation Results for the Software Update
   for the Internet of Things (SUIT) Workflow Model.  Consecutively,
   this document is in support of the Trusted Execution Environment
   Provisioning (TEEP) architecture, which defines the assessment of
   remote peers via RATS and uses SUIT for evidence generation as well
   as a remediation measure to improve trustworthiness of given remote
   peers.
