摘要
简要地介绍了有关椭圆曲线(Ellipticcurve)的数学知识,提出了一种基于投影坐标的ECC快速点乘算法。从实现的角度,对在椭圆曲线密码体制中的运算(点乘)进行了侧信道攻击分析,并对该算法进行了安全性改进。
In this article,the mathematics knowledge about elliptic curve is introduced briefly.We put forward a fast algorithm for point multiplication by use of projective coordinates,and analyze the possible side channel attack during the process of point multiplication.Furthermore,we modify the algorithm for stronger security.
