                    draft-prorock-spice-use-cases-00

Abstract

   This document describes various use cases related to credential
   exchange in a three party model (issuer, holder, verifier).  These
   use cases aid in the identification of which Secure Patterns for
   Internet CrEdentials (SPICE) are most in need of specification or
   detailed documentation.

3.  Introduction

   There are several expanding use cases and common patterns that
   motivate the working group and broader community, including:

   *  Use of microcredentials, particularly in education
   *  Digitization of physical supply chain credentials in multiple
      jurisdictions
      -  CBOR credentials
      -  High volume with system to system exchange of credentions
      -  both regulatory data as well as business driven information
   *  IoT, Control Systems, and Critical Infrastructure related
      Credentials
   *  Credentials related to authenticity and provenance, especially of
      digital media
   *  Offline exchange (in person) of credentials that may have been
      internet issued
