随机预言模型下可证安全的门限FFS签名方案
Provably secure threshold FFS signature scheme in the random oracle model
摘要
Abstract
A rigorous security proof of a provably adaptively-secure optimal-resilience threshold Feige-Fiat-Shamir signature scheme based on strong RSA assumption is given. In the case of the random oracle model, if the basic Feige-Fiat-Shamir signature scheme is unforgeable against the adaptive chosen message attack, and computing the discrete logarithm modulo a safe prime is hard, the new scheme can be proved to be unforgeable, robust and secure against adaptive adversary.关键词
