摘要
提出一种求S—盒的布尔函数表达式的系统方法,并由此法推出了DES中所有S—盒的布尔函数表达式,根据这些布尔函数表达式又导出了DES中S—盒的几点简单性质。
This paper presents a systematical method to get the Boolean function expressions of S-box and in implies all Boolean function expressions of each S-box DES.On basis of these expressions,some properties of S-boxs in DES are concluded.
