RFC 9338, “CBOR Object Signing and Encryption : Countersignatures”, is an Internet Standard document published in December 2022 by J. Schaad. It updates RFC 9052. The canonical text is published by the RFC Editor.
Abstract
Concise Binary Object Representation (CBOR) is a data format designed for small code size and small message size. CBOR Object Signing and Encryption (COSE) defines a set of security services for CBOR. This document defines a countersignature algorithm along with the needed header parameters and CBOR tags for COSE. This document updates RFC 9052.
