    abstract =  {This document describes an extension of the RFC8366 Voucher Artifact in order to support delegation of signing authority. The initial voucher pins a public identity, and that public indentity can then issue additional vouchers. This chain of authorization can support permission-less resale of devices, as well as guarding against business failure of the BRSKI {[}I-D.ietf-anima-bootstrapping-keyinfra{]} Manufacturer Authorized Signing Authority (MASA).},
