Junge Zhao · Jisuanji gongcheng · 2012
The algorithm able to resist power analysis attacks for elliptic curve cryptogram is always inefficient.Aiming at the problem,the method of equivalent consumption coding is applied to scalar multiplication of elliptic curve cryptogram,so that it is able to resist power analysis attacks by removing the power difference in scalar multiplication to cover the related key information.Theoretical analysis shows that the improved algorithm has higher efficiency comparing with binary representation power analysis attack algorithm and NAF window method of power analysis attack algorithm.
