Therefore in recent, the research about bilinear mapping based group signature is also at a start stage, there are no a bilinear mapping based group signature scheme obtains common recognition. There are some design defects in existing schemes, and the security is not very ideal.

所以目前基于双线性映射的群签名还处于一个起步阶段，还没有一个有代表性的基于双线性映射的群签名方案，而现有的一些基于双线性映射的群签名方案的设计缺陷较多，且安全性较差。

Though analyzed the existing schemes, a bilinear mapping based group signature scheme with multi-security strategies proposed, the proposed scheme satisfy the all security requirements for group signature completely.

在对现有的方案进行分析的基础上，提出了一个具有多种安全策略的基于双线性映射的群签名方案，方案很好地满足了群签名的全部安全需求。
