摘要: 通过构造一组正交的Bent函数(序列),利用它进一步构造出一类具有高非线性度、满足SAC的平衡函数,得到比较广泛的结果。

关键词: 平衡函数, Bent函数, 正交Bent序列, 级联, 非线性度, SAC

Abstract: It is constructed that a class of orthogonal Bent sequences, and used them to get balanced functions with high nonlinearity and satisfying SAC. The results are more extending.

Key words: balanced function, Bent function, orthogonal Bent sequence, concatenation, nonlinearity, strict avalanche criterion(SAC)
