Title:
Proofs of Knowledge on Monotone Predicates and its Application to Attribute-Based Identifications and Signatures
Authors: Hiroaki Anada, Seiko Arita, Kouichi Sakurai
Abstract:We propose a concrete procedure of the \Sigma-protocol introduced by Cramer, Damgård and Schoenmakers at CRYPTO '94, which is for proving knowledge that a set of witnesses satisfies a monotone predicate in witness-indistinguishable way; that is, hiding the assignment of truth in the predicate. We provide a detailed procedure by extending the so-called OR-proof.
