Abstract

   This document defines YANG RPC and a minimal datastore required to
   retrieve integrity evidence about software from the device running
   the YANG datastore.  The module presented requires a TPM 2.0 and
   corresponding Trusted Software Stack included in the system entity
   the YANG datastore is running on.
