基于卡方统计量的多差分攻击方法
Multiple Differential Cryptanalysis Using Chi-Square Statistics
摘要
Abstract
In order to evaluate the capability that block ciphers resist differential attack accurately ,a multiple differential cryptanalysis method is proposed in which chi-square statistics is constructed based on multiple differential characteristics with high probablities .We analyze the probability distribution of statistics corresponding correct key and incorrect key ,and give the relation of data complexity ,computational complexity and success probability .We point that the multiple differential cryptanalysis method can be applied to the the instance when the probabilities of differential characteristics are unknown .关键词
