对一个椭圆曲线数字签名方案的攻击分析与改进
ATTACK ANALYSIS AND IMPROVEMENT ON AN ELLIPTIC CURVE DIGITAL SIG NATURE ALGORITHM
摘要
Abstract
We analyse and improve an elliptic curve digital signature algorithm proposed by Zhang Qing-Sheng,et al.and present two kinds of forgery attack algorithm.The cause of the signature forgery is analysed,and a fastest signature scheme is presented,in it the num-bers of both model multiplication and model inverse reach the minimum two times and zero times.Finally,simulation experiment is applied to the proposed signature scheme,the operation comparison with two existing signature algorithms is conducted as well,the signature speed has been increased remarkably.关键词
