This document defines the YANG Remote Procedure Calls (RPCs) and
configuration nodes that are required to retrieve attestation
evidence about integrity measurements from a device, following the
operational context defined in RFC 9683 "TPM-based Network Device
Remote Integrity Verification". Complementary measurement logs
originating from one or more Roots of Trust for Measurement (RTMs)
are also provided by the YANG RPCs.  The defined module requires the
inclusion of the following in the device components of the composite
device on which the YANG server is running: at least one Trusted
Platform Module (TPM) of either version 1.2 or 2.0 as well as a
corresponding TPM Software Stack (TSS), or an equivalent hardware
implementation that includes the protected capabilities as provided
by TPMs as well as a corresponding software stack.

This document is a product of the Remote ATtestation ProcedureS Working Group 
of the IETF.

This is now a Proposed Standard.

STANDARDS TRACK: This document specifies an Internet Standards Track
protocol for the Internet community, and requests discussion and suggestions
for improvements.  Please refer to the current edition of the Official
Internet Protocol Standards (https://www.rfc-editor.org/standards) for the 
standardization state and status of this protocol.  Distribution of this 
memo is unlimited.
