| scope | W3C “Verifiable Credentials†(VCs) is an open standard for digital credentials. A verifiable credential is a tamper-evident credential with authorship that can be cryptographically verified. The W3C standard intentionally does not specify a single verification (“proof†) method, but expects several methods to mature independently and become standardized in time. To guarantee interoperability, W3C maintains a registry of proof mechanisms (including several “experimental†ones) known as Verifiable Credentials Extension Registry. This work item will define a new proof method via a challenge-response authentication protocol based on Ciphertext Policy Attribute-Based Encryption (CP-ABE). In this proof method, CP-ABE keys encode attributes, while the expressiveness of CP-ABE policies enables their selective disclosure and/or proof of predicates over them. Relationship with existing “Zero Knowledge Proof†methods will be highlighted. |
