A Voucher Artifact for Bootstrapping Protocols
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 defines an artifact format as a YANG-defined JSON
document that has been signed using a Cryptographic Message Syntax
(CMS) structure. Other YANG-derived formats are possible. The
voucher artifact is normally generated by the pledge's manufacturer
(i.e., the Manufacturer Authorized Signing Authority (MASA)).
This document only defines the voucher artifact, leaving it to other
documents to describe specialized protocols for accessing it.
