一种基于椭圆曲线的数字签名与盲签名方案

A Scheme Based on the Elliptic Curve Digital Signature and Blind Signature

椭圆曲线数字签名算法实际上是数字签名算法的椭圆曲线模拟,本文在ANSI(1999)颁布的椭圆曲线数字签名(ECDSA)标准的基础上,提出了椭圆曲线数字签名的一个变形方案,并设计了一种新的基于椭圆曲线的盲数字签名方案,其安全性是建立在椭圆曲线离散对数问题的难解性基础上的,从理论上讲是安全的,具有一定的实用价值。

Elliptic curve digital signature algorithm is the elliptic curve analogue of the digital signature al- gorithm. This paper proposes a varied form of elliptic curve digital signature scheme by ANSI（1999） stand- ard and a new blind digital signature scheme based on the elliptic curve cryptosystem. The safety of this scheme is based on the difficulty of solving the elliptic curve discrete logarithm problem. The scheme is secure in theory and is suitable for some practical application.
