Constant-Round Concurrent Zero-knowledge from Indistinguishability Obfuscation

Kai-Min Chung, Huijia Lin, and Rafael Pass

Abstract

We present a constant-round concurrent zero-knowledge protocol for NP. Our protocol relies on the existence of families of collision-resistant hash functions, one-way permutations, and indistinguishability obfuscators for P/poly (with slightly super-polynomial security).
