| 摘 要： | 为了增强代理签名的安全性,在分析现有代理签名方案的基础上,提出了一种基于超椭圆曲线的代理签名方案,同时对该方案的安全性进行了分析.本方案通过将代理签名算法移植入超椭圆曲线密码体制,构造出一种基于超椭圆曲线的代理签名算法.基于超椭圆曲线密码体制代理签名比椭圆曲线在安全性上有显著提高,在电子商务和网络安全中有很好的应用价值.

| Abstract: | To strengthen proxy signature security,and based on the analysis of blind signature scheme in being,this paper proposed a proxy signature scheme based on the hyperelliptic curve cryptography.Furthermore,it analyzed the security problem.Through transplanting a proxy signature arithmetic into hyperelliptic curve cryptography,it proposed a proxy signature arithmetic which was based on the hyperelliptic curve cryptography.Proxy signature scheme based on the hyperelliptic curve cryptography is better than that o... |
