摘要
研究椭圆曲线密码(ECC)算法及符号变换故障攻击原理,提出一种改进的符号变换故障攻击算法。该算法通过改变故障注入位置,减少故障对私钥的数值依赖,有效地解决原算法中出现的"零块失效"问题。采用改进算法对二进制方法点乘的ECC进行符号变换故障攻击,通过仿真实验验证该算法的可行性。
Researching the algorithm of Elliptic Curve Cryptosystems(ECC) and the principle of sign change fault attacks,this paper presents an improved algorithm of sign change fault attacks which can effectively solve the "zero block failure" problem and reduce the dependence of faults on private key by changing the location of induced faults.Using the improved algorithm attacks on ECC with binary scalar multiplication,simulation experiment verifies the feasibility of the algorithm.
