借助置换函数的性质和构造,找到了布尔函数是超Bent函数的充要条件以及超Bent函数与PS类Bent函数的关系. 给出了多输出超Bent函数的一般构造方法,并利用这种方法构造了具有高非线性度的平衡多输出函数.
Using the properties and constructions of permutations, one sufficient and necessary condition for Boolean functions being hyper-Bent functions and the relation between hyper-Bent functions and PS class Bent functions are provided. One generalized method to construct multi-output hyperBent functions and balanced multi-output functions with high nonlinearity is presented.
