摘要 如何有效地提高效率和如何安全地撤消成员是阻碍群签名走向实际应用的两个主要问题。文章对ACJT群签名及其成员撤消方案进行了一些改进,提出了一个新的方案,在保证不影响其安全性的前提下使其效率得到显著提高。量化分析表明:新方案与原方案相比,签名长度缩短了58%,运算次数减少了26%,并能满足群签名的所有安全要求。 How to improve the efficiency and how to delete group members securely are two important issues that stand in the way of real-world applications of group signatures scheme.In this paper,an improvement of ACJT group signature scheme and its member revocation is made by improving the efficiency remarkably while not reducing the security. Quantized analysis shows that the length of the signature is shorten by 56%,the number of the operation is reduced by 26%.
