摘要/Abstract

摘要：

结合多篇文献发现现有的方案并不高效，在文献［5］的基础上提出了一种高效的无证书代理盲签名方案。本方案通过对部分密钥的适当修改来减少双线性对运算；同时，由于网络服务的不断提升，利用通讯耗时替代运算耗时同样能够提升效率。与多种方案的签名算法与验证算法作效率分析对比得出，该方案在效率上具有极大的提升，且方案满足不可伪造性、不可否认性、可鉴别性和盲性等性质。

Abstract:

Considering that multiple references found that the existing scheme is not efficient, based on reference［5］, it proposes a certificateless proxy blind signature scheme with high efficiency. The scheme is based on the appropriate modification of partial key to reduce the operation time of bilinear pairings. Meanwhile, due to the continuous improvement of the network service, replacing the operation time by the communication time can improve the efficiency. By comparing the proposal with various signature algorithms and verification algorithms, it is proved that our scheme improves the efficiency greatly and satisfies unforgeability, nonrepudiation, identification, blindness, etc.
