基于ElGamal签名体制，设计了一个安全有效的群签名方案。方案把群管理者分成两部分GM1和GM2， GM1负责群成员的加入和群成员私钥的发行，如果发生争执，GM2负责打开群签名信息并可以执行追踪，这种方法安全有效地实现了群中成员动态添加和删除，提高了群签名方案的安全性和实用性，为群签名方案的设计及运用提供了一种有效的实现途径。
基于ElGamal籤名體製，設計瞭一箇安全有效的群籤名方案。方案把群管理者分成兩部分GM1和GM2， GM1負責群成員的加入和群成員私鑰的髮行，如果髮生爭執，GM2負責打開群籤名信息併可以執行追蹤，這種方法安全有效地實現瞭群中成員動態添加和刪除，提高瞭群籤名方案的安全性和實用性，為群籤名方案的設計及運用提供瞭一種有效的實現途徑。

Based on ElGamal signature system ,a security and efficient group signature scheme is designed .The group managers are divided into parts of GM1 and GM2 .GM1 is responsible for the group members joining and distributing the pri‐vate‐key to the group members ,another group managers ,and GM2 is responsible for showing and tracking messages of the group signature when a dispute takes place .This method is secure and effective for the group members adding and removing dynamically ,improving the safety and practicability of the group signature scheme ,providing an effective approach for the group signature scheme in design and application .
