Constrictions of bent functions using a family of permutations and ReedMuller type codes
Abstract:
From a pair of permutations of the first n integers we get a family of permutations on 2^n objects. This family provides new bent functions ie Boolean sequences of length 2^(2n) whose Walsh transfom get values in {2^n, 2^n}. The left half of a bent function determines a nearbent i.e., Boolean sequences of length 2^n (n odd) with Walsh spectrum in {0,2^n,2^n} . We relate the support of nearbents with Reed  Muller type codes and using this we construct bents of higher degree using RM type codes and bents of lower type. We also discuss several ways for constructing bent functions and modify wellknown constructions as for example Dillon H class and Maiorana McFarland method.
