in computer and other communication networks, the reliability of the information and the integrity of the information is an important communications security issues, particularly in unsafe channel communications, verification of the message is indispensable, there are many ways to solve these problems, this paper provides a method of message authentication.

在计算机及其他通信网络中，对消息的可靠性及完整性的验证是通信安全的重要问题，特别是在不安全的信道通信时，对消息的验证更是不可缺少的，解决此类问题的方法有很多，本文提出了一种消息认证的方案。

Finally this thesis analyses the efficient revocable group signature scheme with forward security proposed by Chen Shaozhen and Li Daxirig. An adversary can personate a legal group member by forge a group membership certificate, and then can forge group signatures that can be verified by a verifier. And the group manager can also forge group signatures that can be verified by a verifier. So the scheme is insecure. Meanwhile, there are redundancy steps in the scheme, thus the efficiency is low.

接着，对陈少真和李大兴提出的一种有效取消的前向安全群签名方案进行了密码学分析，一方面，攻击者可以通过伪造群成员证书来伪造能够通过验证的群签名；同时，群管理员也可以伪造一个可以通过验证的群签名，因此，该群签名体制是不安全的；另一方面，该体制存在冗余数据。

In order to ensure information management and function validity, it is significance that researching secure communication based on insecure network.

为了保障信息的管理和服务职能的有效实现，研究在不安全的网络环境下，进行安全的数据传输是很有意义的。
