Abstract: 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.
