基于椭圆曲线的代理盲签名新方案

A New Proxy Blind Signature Scheme Based on Elliptic Curve

结合代理签名和盲签名的特性,设计了一个新的基于椭圆曲线的代理盲签名方案。该方案的安全性是建立在目前还没有有效攻击方法的有限域上非超奇异椭圆曲线的离散对数问题之上的,理论分析该方案安全、实用。

This paper proposes a new proxy blind signature scheme based on elliptic curve,which combines the specialty of the proxy signature and the blind signature.The safety of this scheme is based on the elliptic curve discrete logarithm of nonsupersingular elliptic curve over finite field which has no efficient attack method by now.The new scheme is secure and is suitable for some practice.
