摘要 黄振杰等人提出了授权群签名方案并称此方案有效,对此进行详细分析发现存在两个缺陷。提出一种攻击方案,使得任何一个群成员可以用伪造的签名通过验证,但是群管理员对签名者却无法识别。 Huang ZJ proposed an authorised group signature scheme and claimed that it is efficient. This paper carefully analyzed it and found two defects, then gave a forgery attack, and anyone in the group can produce a valid group signature with the forgery attack, but the group manager can not identify the signer.
