JSON Web Proofs

Specification work for JSON Web Proofs

The JSON Web Proofs effort aims to establish a new JSON based container as a new entry in the JOSE family of container formats.

While similar to JSON Web Signatures¹, JSON Web Proofs aim to support newer algorithms and cryptographic techniques. These techniques establish the role of a prover, which has limited capabilities to derive new forms of from a signed message which can still be cryptographically verified.

Examples of capabilities an algorithm may support include:

Selectively disclose a subset of information to the verifier
Provide for multiple uses of a proof container without correlation due to cryptography
Disclose an answer to a predicate without disclosing the values used for evaluation
Proof of possession

Specifications in Progress

JSON Web Proof

A new container, similar to JWS¹, which allows for more than one payload.

JSON Proof Algorithms

Required and optional capabilities for algorithms within JSON Web Proofs.

This is loosely analogous to JWA², with concrete algorithms defined as separate specifications.

JSON Proof Token

An application of JWP for representing claims about an entity, analogous to JWT³.
