部分Bent函数的几种构造方法

Several Methods of Constructing Partially-bent Functions

给出了部分Bent函数几种一般性构造方法 ,同时得到了由上述方法所构造出的部分Bent函数的Walsh循环谱特征 .特别给出了由变元个数少的Bent函数构造变元个数多的部分Bent函数的一般方法 。

Several generalized methods of constructing partially-bent functions are presented. Meanwhile the Walsh cyclic spectrum characteristics of these partially-bent functions are shown.In addition,the method of constructing partially-bent functions with more variables by bent functions with less variables.
