A YANG Data Model for Challenge-Response-based Remote Attestation
Procedures using TPMs
draft-ietf-rats-yang-tpm-charra-02
Abstract
This document defines a YANG RPC and a minimal datastore tree
required to retrieve attestation evidence about integrity
measurements from a composite device with one or more roots of trust
for reporting. 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 interaction model and
information elements defined in the
[I-D.birkholz-rats-reference-interaction-model] document. The
currently supported hardware security modules (HWM) - sometimes also
referred to as an embedded secure element (eSE) - is the Trusted
Platform Module (TPM) version 1.2 and 2.0 specified by the Trusted
Computing Group (TCG). One ore more TPMs embedded in the components
of a composite device - sometimes also referred to as an aggregate
