Title:
Four-round Statistical Non-malleable Zero-knowledge
Authors: Susumu Kiyoshima
Abstract:We present a 4-round statistical non-malleable zero-knowledge (NMZK) argument in the plain model under standard hardness assumptions. Our construction can be based on any collision-resistant hash function and injective one-way function, and it guarantees simulation extractability in the delayed-input one-many setting. Before this work, 4-round constructions were known for computational NMZK but not for statistical NMZK.
