       Using Netconf Pub/Sub Model for RATS Interaction Procedure
                     draft-xia-rats-pubsub-model-01

Abstract

   This draft defines the a new method of using the netconf pub/sub
   model in the RATS interaction procedure, to increse its flexibility,
   efficiency and scalability.

1.  Introduction

   Remote attestation is for acquiring the evidence about various
   integrity information from remote endpoints to assess its
   trustworthiness (aka, behave in the expected manner).  These evidence
   should be about: system component identity, composition of system
   components, roots of trust, system component integrity, system
   component configuration, operational state and so on.
   [I-D.richardson-rats-usecases] describes possible use cases which
   remote attestation are using for different industries, like: network
   devices, FIDO authentication for onlline transaction, Cryptographic
   Key Attestation for mobile devices, and so on.

   [I-D.birkholz-rats-architecture] lays a foundation of RATS
   architecture about the key RATS roles (i.e., Relying Party, Verifier,
   Attester and asserter) and the messages they exchange, as well as
   some key concepts.  Based on it,
   [I-D.birkholz-rats-reference-interaction-model] specifies a basic
   challenge-response-based interaction model for the remote attestation
   procedure, which a complete remote attestation procedure is triggered
   by a challenge message originated from the verifier, and finished
   when the attester sends its response message back.  This is a very
   generic interaction model with wide adoption.  This document proposes
