Abstract

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.

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。
