摘要: 给出了一类广义Bent函数的递归构造方法,并讨论了它们的性质,这类广义Bent函数具有高非线性性,平衡性,且具有一致相关值,并且当k满足(3≤k≤n-1)时可构造出任意k次的广义Bent函数,亦即在GF(2)~n上存在满足上述性质的n-1次广义Bent函数。

关键词: Bent函数, 广义Bent函数, 平衡函数, 非线性度

Abstract: Gives a construction method of a kind extensive bent functions, with degree k(3≤k≤n-1),which have the properties of highly nonlinear degree, balanced and uniform correlation value.

Key words: bent function, extensive bent function, nonlinear degree
