Title: On Designs and Multiplier Groups Constructed from Almost Perfect Nonlinear Functions

Authors: Yves Edel and Alexander Pott

Abstract: Let f : F_2^n to F_2^n be an almost perfect nonlinear function (APN). The set D_f := {(a, b) : f(x + a) - f(x) = b has two solutions} can be used to distinguish APN functions up to equivalence. We investigate the multiplier groups of these sets D_f. This extends earlier work done by the authors.
