Abstract
Pott et al. (2018) showed that F(x) = x2r Trn m(x), n = 2m, r ≥ 1, is a nontrivial example of a vectorial function with the maximal possible number 2n 2m of bent components. Mesnager et al. (2019) generalized this result by showing conditions on Λ(x) = x+ ∑σ j=1 αjx2tj, αj ∈ 2 F2m, under which F(x) = x2r Trn m(Λ(x)) has the maximal possible number of bent components. We simplify these conditions and further analyse this class of functions. For all related vectorial bent functions F(x) = Trn m(γF(x)), γ ∈ 2 F2n F2m, which as we will point out belong to the MaioranaMcFarland class, we describe the collection of the solution spaces for the linear equations DaF(x) = F(x) + F(x + a) + F(a) = 0, which forms a spread of F2n. Analysing these spreads, we can infer neat conditions for functions H(x) = (F(x);G(x)) from F2n to F2m × F2m to exhibit small differential uniformity (for instance for Λ(x) = x and r = 0 this fact is used in the construction of Carlet’s, PottZhou’s, Taniguchi’s APNfunction). For some classes of H(x) we determine differential uniformity and with a method based on Bezout’s theorem nonlineariy.
