摘要
本文首先利用布尔函数的特征集合对布尔函数的线性结构进行了刻划,给出了寻找布尔函数的线性结构的一种方法。其次引入了布尔函数的r型线性结构的概念,并对其进行了研究,同时还指出了布尔函数的r型线性结构的密码学意义。
The linear structures of Boolean functions are discussed using characteristic set of Boolean functions, and a way to find linear structures of Boolean functions is given. Then, the linear structures of Boolean functions are generalized, and r-type linear structures of Boolean functions are presented and studied, meanwhile the cryptological significance of r-type linear structures of Boolean functions is described.
