Abstract

The present document defines a new proof method via a challenge-response authentication protocol based on predicate encryption, in particular on Ciphertext Policy-Attribute Based Encryption (CPABE). In this proof method, CP-ABE keys encode attributes, while the expressiveness of CP-ABE policies enables their selective disclosure and/or anonymous proof of predicates over them. Relationship with existing Zero Knowledge Proof [i.16] methods is highlighted.
