           Use cases for Remote Attestation common encodings
                   draft-richardson-rats-usecases-02

Abstract

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

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

1.  Introduction

   The recently chartered IETF RATS WG intends to create a system of
   attestations that can be shared across a multitude of different
   users.

   This document exists as place to collect use cases for the common
   RATS technologies in support of the IETF RATS charter point 1.  This
   document is not expected to be published as an RFC, but remain open
   as a working document.  It could become an appendix to provide
   motivation for a protocol standards document.

   This document will probably not deal with use cases from an end-user
   point of view, but rather on the technology verticals that wish to
   use RATS concepts (such as EAT) in their deployments.

   End-user use cases that would either directly leverage RATS
   technology, or would serve to inform technology choices are welcome,
   however.

2.  Terminology

   Critical to dealing with and constrasting different technologies is
   to collect terms with are compatible, to distinguish those terms
   which are similar but used in different ways.
