摘　　要：对赵树平等人提出的群签名方案进行了分析,发现此方案不具有动态性.根据矢量空间秘密共享知识,通过给定秘密,在加入或删除成员时每个成员的子秘密随之变化,以此提出一种基于双线性对的动态群签名方案.研究分析表明,此方案是安全的,同时又提高了签名效率.The Zhao et al group signature scheme was analyzed,and we find this scheme do not have dynamic. According to the vector space secret sharing, through a regular secret , when add or remove members of group, the sub-secret of each member have changed, there- fore,a dynamic group signature scheme based on bilinear pairing is proposed. Analysis shows that this scheme is secure. Besides, this scheme has also improved the efficiency of the original signature scheme.
