摘要
对已知的Bent序列集的构造方法作了研究,明确地给出了任一Bent序列集相关值的分配情况.同时,利用有限域上一类新的Bent函数,构造出了一类新的Bent序列集,给出了这类Bent序列的线性复杂度.
The construction methods of Bent-function sequences are studied and the correlation distribution of Bent-function sequences is determined. A new class of binary bent-function sequences are constructed and the linear span of these sequences are also derived.
