       Constrained Voucher Artifacts for Bootstrapping Protocols
                draft-ietf-anima-constrained-voucher-09

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".

   This document builds upon the work in [RFC8366], encoding the
   resulting artifact in CBOR.  Use with two signature technologies are
   described.

   Additionally, this document explains how constrained vouchers may be
   transported as an extension to the [I-D.ietf-ace-coap-est] protocol.
