%X Analysis of how to transform Doubling attack to attack Koblitz curve of the scalar multiplication was given. A randomized method for input points by using point halving was proposed, which was integrated with Koblitz curve of fixed window algorithm, to resist the side channel attack. The analysis demonstrates that the method can not only resist Simple Power Analysis (SPA), Differential Power Analysis (DPA), Refined Differential Power Analysis (RPA), Zero-value Power Attack (ZPA) and Doubling attack, but also has efficient and practical significance.
