Abstract

Three classes of Boolean functions with four-valued Walsh spectra are presented and their Walsh spectrum distributions are determined. They are derived from Bent functions of the Maiorana-McFarland and Dillon PSap types and of the monomial form \(Tr_1^{2m} (\lambda x^{r(2^m - 1)} )\) by complementing the values of the Bent functions at two points.
