Thrifty Zero-Knowledge - When Linear Programming Meets Cryptography
Simon Cogliani and Houda Ferradi and Rémi Géraud and David Naccache
Abstract
We introduce “thrifty” zero-knowledge protocols, or TZK. These protocols are constructed by introducing a bias in the challenge send by the prover. This bias is chosen so as to maximize the security versus effort trade-off. We illustrate the benefits of this approach on several well-known zero-knowledge protocols.
