摘要
对"与常数模2n加"即Y=(X+K)mod2n的不可能差分性质进行了研究,首次给出了当差分转移概率取值为0时,输入差ΔX、输出差ΔY及常数K的结构特点和计数下界。
The impossible differential property of an added constant on modulo 2n operation Y=X ＋ Kmod 2n is studied. The characters of the structure and the lower bound of numbers of the input difference AX, the output difference AY and the constant K are given for the first time as the differential probability is to be 0.
