摘　　要：对Ｈｅ 和Ｗｕ 基于二次剩余问题设计的快速数字签名方案（简称Ｈ－Ｗ 数字签名方案）的安全性进行了分析， 指出Ｈ－Ｗ 数字签名方案是不安全的， 并利用Ｍｏｒｒｉｓｏｎ－Ｂｒｉｌｌｈａｒｔ素因子分解算法，We will analysis the security of the fast digital signature scheme, which is proposed designed by He and Wu based on quadratic residue (called H W digital signature scheme). And point out that the scheme is insecure. We also present an attack method, which is based on Morrison Brillhart's factoring, on H W digital signature scheme.

关 键 词：密码学 数字签名 二次剩余
