Computing an integral multiple of an element of a group is basic to all algorithms in cryptography. It is commonly based on the binary notation system. 计算群元素的整数倍是一切密码算法的基础,通常是采用整数的二进制表示。
Moreover, when the standard binary notation system was adopted to compute the integral multiple of an element of a group, the time can be saved approximately by 1/ 4. 在引进标准二进制计算群元素的情况下,还能节约1/4计算量。
