A YANG Data Model for Challenge-Response-based Remote Attestation
Procedures using TPMs
draft-ietf-rats-yang-tpm-charra-05
Abstract
This document defines a YANG RPC and a minimal datastore required to
retrieve attestation evidence about integrity measurements from a
device following the operational context defined in TPM-based Network
Device Remote Integrity Verification. Complementary measurement logs
are also provided by the YANG RPC originating from one or more roots
of trust of measurement. The module defined requires at least one
TPM 1.2 or TPM 2.0 and corresponding Trusted Software Stack included
in the device components of the composite device the YANG server is
running on.

1. Introduction
This document is based on the terminology defined in the
[I-D.ietf-rats-architecture] and uses the operational context defined
in [I-D.ietf-rats-tpm-based-network-device-attest] as well as the
interaction model and information elements defined in
[I-D.ietf-rats-reference-interaction-models]. The currently
supported hardware security modules (HWM) are the Trusted Platform
Module (TPM) [TPM1.2] and [TPM2.0] specified by the Trusted Computing
Group (TCG). One ore more TPMs embedded in the components of a
