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.
