Title:
Making Groth’s zk-SNARK Simulation Extractable in the Random Oracle Model
Authors: Sean Bowe, Ariel Gabizon
Abstract:We describe a variant of Groth’s zk-SNARK [Groth, Eurocrypt 2016] that satisfies simulation extractability, which is a strong form of adaptive non-malleability. The proving time is almost identical to [Groth] and requires only two additional group operations. Our proof consists of 5 group elements rather than 3 as in [Groth], and the security proof requires the random oracle model.
