摘要
2000年,Chen-Zhu提出了一种优于已有方案的群签名方案。该文认为该方案是全局可伪造的,群管理员可以对任何消息假冒任何成员生成有效的群签名。
In 2000,Chen- Zhu proposed a group signature scheme that is more efficient than the previously known schemes. This paper shows that Chen- Zhu's scheme is universally forgeable, that is, the group authority can forge a valid group signature on an arbitrary message, which stands in any group member.
