| 摘 要： | 基于ElGamal密码体制及其签名算法,构造了一个高效安全的群签名方案。在签名初始化阶段,把群管理者分成两个部分T1和T2, T1负责签名群成员的加入,删除和密钥发行。如果发生争端需要仲裁,那么可由T2负责打开群签名并进行追踪,这种方法有效地实现了签名群中成员的动态管理,具有一定的高效性、安全性和实用性。方案给出了详细的设计过程,并对其高效性和安全性进行了分析,为群签名方案的设计与实现提供了一种参考。

| Abstract: | Based on ElGamal signature system, an efficient group-signature scheme is proposed. In the initialization phase of signature, the group-manager is divided into two parts——T1 and T2,T1 is responsible for the accession and deletion of group members and distribution of secret-key for the group members. In case of dispute, T2 is responsible for opening group-signature and tracking. This scheme could effectively achieve dynamic management of the group-signature,and has certain efficiency, safety and practicability. A detailed design is given, and its efficiency and security analyzed. This may serve as a reference for the design and implementation of group-signature scheme. |
