This specification describes how to declare in a CBOR Web Token (CWT)
(which is defined by RFC 8392) that the presenter of the CWT
possesses a particular proof-of-possession key. Being able to prove
possession of a key is also sometimes described as being the
holder-of-key. This specification provides equivalent functionality
to "Proof-of-Possession Key Semantics for JSON Web Tokens (JWTs)"
(RFC 7800) but using Concise Binary Object Representation (CBOR) and
CWTs rather than JavaScript Object Notation (JSON) and JSON Web
Tokens (JWTs).

This document is a product of the Authentication and Authorization for Constrained Environments Working Group of the IETF.

This is now a Proposed Standard.

STANDARDS TRACK: This document specifies an Internet Standards Track
protocol for the Internet community, and requests discussion and suggestions
for improvements.  Please refer to the current edition of the Official
Internet Protocol Standards (https://www.rfc-editor.org/standards) for the 
standardization state and status of this protocol.  Distribution of this 
memo is unlimited.
