一种基于椭圆曲线的Optimal型盲签名方案

An Optimal Type Blind Digital Signature Scheme Based on Elliptic Curves

椭圆曲线数字签名实际上是基于乘法群的离散对数问题的数字签名在椭圆曲线上的模拟。利用椭圆曲线来改进Optimal盲签名方案,并对其完备性、不可伪造性、安全性、盲性进行了分析。

The elliptic curve digital signature is the elliptic curve analogue of digital signature based on discrete logarithm of multiplicative group. It is pointed out that the optimal type blind digital signature scheme is improved by the elliptic curve with detailed analysis on its completeness, un-forgeability, security and blindness.
