Reference Integrity Measurement Extension for Concise Software
Identities
draft-birkholz-rats-coswid-rim-02
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
