摘要: 对一个基于RSA的群签名方案提出安全性分析,指出它存在以下安全缺陷:(1)群中心可以伪造公钥状态列表中的任意一个群成员的签名;(2)群成员可以生成不可追踪的群签名;(3)群成员或签名验证者可以伪装成群中心发布密钥;(4)群管理员可以陷害公钥状态列表中的任意一个群成员。

Abstract: Cryptanalysis of a group signature scheme based on RSA shows that it exists follow security flaws:(1)group centre can forge any group member’s signature on condition that the member’s public key is kept in the PKSL;(2)group member can generate a group signature that it can not be traced;(3)either group member or the signature verifier can announce key on behalf of the group centre;(4)group manager can frame up any group member if member’s key is kept in the PKSL.
