Simple power analysis is the most devastating attack on the security of elliptic curve scalar multiplication and can probably retrieve the secret key. In this paper, we analyze the formulas of point doubling and addition on Jacobi-quartic Curve in projective coordination. In addition, a fast and secure side-channel atomic scalar multiplication algorithm is proposed using the side-channel atomic block. Compared with the previous methods, the new algorithm is more efficient. For 192 bits scalar using NAF recoding, the efficiency of the new algorithm is increased by about 6.7%~23% if S/M=0.8 or 12.7%~33.2% if
S/M=0.6. 相似文献
