摘要
从椭圆曲线加法公式出发,在Comb算法中,运用以折半运算为基础的Comb标量乘算法,减少赋值和预计算期间的运算量,使得椭圆曲线标量乘法的运算效率大幅提高.
From additive formula of the elliptic curve, this paper uses the Comb algorithm based on the point halving algorithm to reduce the evaluation and the amount of computation so as to greatly raise the computation effect for the ellipse scalar multiplication.
