摘　　要：在第三方不可信任的情况下,传统的ID签名系统不适用于安全的群签名。给出一个安全的基于ID的群签名方案,即使在密钥生成中心(KGC)不可信的情况下,也能保证其安全性,而且该方案可以安全地增加或删除群成员而不需要改变其他有效群成员密钥和群公开密钥。同时,密钥的长度及签名的长度与群成员的多少无关。In the case that third parties can not be trusted, the traditional ID signature security system does not suit for the group signature. A secure ID-based group signature scheme was proposed. Even when the Key Generation Center （KGC） was implausible, its safety could be ensured, and the group members could be safely added or deleted without changing the keys of other effective group members and public group key. At the same time, the lengths of key and signature were unrelated to the number of group members.
