The JOSE specifications are very widely deployed and well supported, enabling use of cryptographic primitives with a JSON representation. JWTs [@RFC7519] are one of the most common representations for identity and access claims. For instance, they are used by the OpenID Connect and Secure Telephony Identity Revisited (STIR) standards. Also, JWTs are used by W3C's Verifiable Credentials and are used in many decentralized identity systems.

With these new use cases, there is an increased focus on adopting privacy-protecting cryptographic primitives. While such primitives are still an active area of academic and applied research, the leading candidates introduce new patterns that are not currently supported by JOSE or COSE. These new patterns are largely focused on two areas: supporting selective disclosure when presenting information and minimizing correlation through the use of Zero-Knowledge Proofs (ZKPs) in addition to traditional signatures.

There are a growing number of these cryptographic primitives that support selective disclosure while protecting privacy across multiple presentations. Examples used in the context of Verifiable Credentials are:
