我们考虑具有 Trace 表示的负布尔函数。据我们所知,这是有史以来第一个关于具有这种表示形式的负函数的工作。我们完全表征了负二次单项函数。我们还给出了 Maiorana-McFarland 弯曲函数为负弯曲函数的充分必要条件。作为该结果的结果,我们提出了基于排列的弯曲负 Maiorana-McFarland 函数的良好表征。
We consider negabent Boolean functions that have Trace representation. To the best of our knowledge, this is the first ever work on negabent functions with such representation. We completely characterize negabent quadratic monomial functions. We also present necessary and sufficient condition for a Maiorana-McFarland bent function to be a negabent function. As a consequence of that result we present a nice characterization of a bent-negabent Maiorana-McFarland function which is based on the permutation.
