摘要： Chaum等在文献[1]中提出群签名的概念。它允许群成员之一代表这个群体对消息进行匿名的签名。如果以后出现争议，设定的群管理员可以打开签名并确定签名者身份。该文基于DSA体制建立了新的有效的群签名体制。

Abstract: The concept of group signature is introduced by Chaum at Eurocrypt'91. It allowes a member of a group to sign messages anonymously on behalf of the group. In case of a later dispute a designated group manager can revoke the anonymity and identify the originator of a signature. this paper proposes a new efficient group signature scheme based on DSA.
