              Voucher Profile for Bootstrapping Protocols
                      draft-ietf-anima-voucher-01

Abstract

   This document defines a strategy to securely assign a pledge to an
   owner, using an artifact signed, directly or indirectly, by the
   pledge's manufacturer.  This artifact is known as a "voucher".

   The voucher artifact is a YANG-defined JSON document that has been
   signed using a PKCS#7 structure.  The voucher artifact is generated
   by the pledge's manufacture or delegate (i.e. the MASA).

   This document only defines the voucher artifact, leaving it to other
   documents to describe specialized protocols for accessing it.

1.  Introduction

   This document defines a strategy to securely assign a pledge to an
   owner, using an artifact signed, directly or indirectly, by the
   pledge's manufacturer or delegate (i.e. the MASA).  This artifact is
   known as the voucher.

   The voucher artifact is a JSON document, conforming to a data model
   described by YANG [RFC7950], that has been signed using a PKCS#7
   structure.
