Title
|
Cyber Security (CYBER); A Verifiable Credentials extension using Attribute-Based Encryption A Verifiable Credentials extension using Attribute-Based Encryption
|
Scope and Field of Application
|
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.
