Sub-linear Size Pairing-based Non-interactive Zero-Knowledge Arguments

Jens Groth

Abstract: We construct non-interactive zero-knowledge arguments for circuit satisfiability and arithmetic circuits with perfect completeness, perfect zero-knowledge and computational (co-)soundness. The non-interactive zero-knowledge arguments have sub-linear size and very efficient public verification. Our construction uses bilinear groups and is only proven secure in the generic group model, but does not rely on random oracles.

Category / Keywords: foundations / Sub-linear size non-interactive zero-knowledge arguments, circuit satisfiability, pairing-based cryptography, generic group model.
