| 摘 要： | 给出一种新的动态群签名的构造方法。该方法以BLS短签名方案为基础，构造出一种签名长度较短、结构简单的群签名方案。方案引入两个群管理员，一个管理员Issuer负责群成员的加入和群成员群密钥的分发；而另一个管理员Opener负责群签名的跟踪。安全性分析表明该方案能够满足群签名方案应该具有的安全性要求。

| Abstract: | A new constructive method of dynamic group signatures was presented.Based on BLS short signature,a short and simple scheme of group signatures was proposed by introducing two group managers.One is responsible for the join of the group member and the distributions of the key;another manages the tracing of the group signature.Results of security analysis show that this scheme can satisfy the security requirements of a group signature. |
