本文在素域上讨论了部分bent函数的谱特征,得到了素域上部分bent函数的几个新的刻画,揭示了部分bent函数的平衡性、线性结构及非零谱值点之间的相互关系,并对部分bent函数的恒变线性结构进行了分类,指出了它们之间的相互关系。 In this paper, the spectral features of some bent functions are discussed in the prime domain, and some new features of some bent functions in the prime domain are obtained. The results show that the balance of some bent functions, the mutual relations between linear structures and non-zero spectral points Relations, and classifies the constant linear structures of some bent functions, pointing out their interrelations.
