Automated Certificate Management Environment (ACME) Remote Attestation Identifier and Challenge Type

This document describes an approach where an ACME Server can challenge an ACME Client to provide Evidence, Endorsements, or Attestation Result according to the Remote ATtestation procedureS (RATS) framework in any format supported by the Conceptual Message Wrapper (CMW). The ACME Server can optionally challenge the Client for specific claims that it wishes attestation for.
