Elliptic curve cryptosystems require shorter key length than traditional cryptosystems. It is good that scalar multiplication algorithm has small computational cost and resistance for side-channel attacks. Regular scalar multiplication has SPA and SEA resistance and is proposed by Marc Joye.
In this paper, we propose more efficient scalar multiplication algorithms with resistance for side-channel attacks on affine coordinate. Computational cost can be reduced by scanning scalar $k$ with 2-bit simultaneously. And to keep resistance for side-channel attacks, we use a fact that computational cost of double-add and triple arithmetic on affine coordinate are same under $S=M$. |
