### Paper: Classes of Quadratic APN Trinomials and Hexanomials and Related Structures

Authors: Lilya Budaghyan Claude Carlet URL: http://eprint.iacr.org/2007/098 Search ePrint Search Google A method for constructing differentially 4-uniform quadratic hexanomials has been recently introduced by J. Dillon. We give various generalizations of this method and we deduce the constructions of new infinite classes of almost perfect nonlinear quadratic trinomials and hexanomials from $\mathbb{F}_{2^{2m}}$ to $\mathbb{F}_{2^{2m}}$. We check for $m=3$ that some of these functions are CCZ-inequivalent to power functions.
