           Use cases for Remote Attestation common encodings
                   draft-richardson-rats-usecases-06

Abstract

   This document details mechanisms created for performing Remote
   Attestation that have been used in a number of industries.  The
   document initially focuses on existing industry verticals, mapping
   terminology used in those specifications to the more abstract
   terminology used by the IETF RATS Working Group.

   The document aspires to describe possible future use cases that would
   be enabled by common formats.
