Some Results on the Known Classes of Quadratic APN Functions

Lilya Budaghyan and Tor Helleseth and Nian Li and Bo Sun

Abstract: In this paper, we determine the Walsh spectra of three classes of quadratic APN functions and we prove that the class of quadratic trinomial APN functions constructed by G\"olo\u glu is affine equivalent to Gold functions.
