摘要
利用椭圆曲线离散对数问题的难解性,提出了三个基于椭圆曲线密码体制的部分盲签名方案,这三个方案可以看作是Schnorr,DSA,Nyberg-Rueppel签名算法的部分盲签名算法在椭圆曲线上的模拟,并对完备性、部分盲特性、不可伪造性、无关联性进行了分析。该方案具有较高的安全性,较低的复杂性。
Three partial blind signature schemes based on the elliptic curve discrete logarithm were proposed.The three schemes can be regarded as Schnorr,DSA,Nyberg-Rueppel partial blind signature schemes simulated on the elliptic curve.The completeness,partial blindness,unforgeability,irrelatedness were also analyzed.This scheme has higher security and lower complexity.
