摘要
为提高差分密码分析的速度 ,提出了一种同时采用两个圈特征的差分分析方法 ,并以简化的 8圈DES为例 ,分别从小存储空间和大存储空间两种情况描述了该方法的具体实施过程 ,包括两种圈特征的选取以及该方法的性能分析 .
In order to increase the speed of differential cryptanalysis, a differential cryptanalysis method was presented by making use of two round characteristics at the same time. DES reduced to 8 rounds was taken as an example to illustrate the specific process of this method from small and large memory space respectively, including the choice of 2 round characteristics and analyzing performance of the method. The method is applicable for differential cryptanalysis of other cryptographies.
