摘要 群签名在数字签名中非常重要,但由于计算复杂和参数过多,使群签名方案易受各种攻击。文章给出群签名方案应满足的条件,对两种群签名方案进行了分析,指出它们的不安全性。 Group signature is very important in the digital signature. Because of the complicacy of calculation and excessive parameters, it can easily be attacked. This paper presents the conditions which group signature should satisfy, analyzes two group signature schemes and points out their insecurity.
