摘要:

通过对一个给定的Bent序列及其级联序列进行四元置换、逐项积的方法,构造出了一个新的Bent序列,所〖JP2〗构造的Bent序列与原Bent序列不具有线性关系. 用该方法还能构造出大量的既非Bent基又非线性基的Bent序列.

关键词: Bent序列, 线性序列, 级联, Walsh Hadamard矩阵

Abstract:

In this paper a new Bent sequence is constructed by 4 permutation and component wise product for a given new Bent sequences and concatation sequence.The constructed Bent sequences and the original Bent sequences isn’t linearly connected,by which a great number of non-Bent based and non-linear based can also be constructed.

Key words: Bent sequences, affine sequences, concatenation, Walsh Hadamard matrix
