Abstract

   This document specifies the CDDL and usage description for Reference
   Integrity Measurements (RIM) in Remote Attestation Procedures (RATS).
   The specification is based on Concise Software Identification
   (CoSWID) and TCG Reference Integrity Manifest Information Model -
   based on Host Integrity at Runtime and Start-up (HIRS).  Extension
   points defined in CoSWID used to augment CoSWID tags with new
   attributes that can express the TCG Reference Integrity Manifest
   extensions.

1.  Introduction

   Reference Integrity Measurements describe the intended state of
   (composite) software components installed on a (composite) device.  A
   measurement of all installed software components of a devices allows
   for assertions about the trustworthiness of the given device.  In
   combination with a root of trust (RoT) for reporting (RTR), these
   measurements can be refined into evidence and enable Remote
   ATtestation procedureS (RATS).  RATS support the decision process of
   whether to put trust in the trustworthiness of a device - or not.

   The RATS architecture [I-D.ietf-rats-architecture] defines the
   following roles: Verifier, Attester, Endorse, and Relying Party, and
   Reference Value Provider.  The RATS architecture also specifies that
