### Paper: On CCZ-equivalence and its use in secondary constructions of bent functions

Authors: Lilya Budaghyan Claude Carlet URL: http://eprint.iacr.org/2009/042 Search ePrint Search Google We prove that, for bent vectorial functions, CCZ-equivalence coincides with EA-equivalence. However, we show that CCZ-equivalence can be used for constructing bent functions which are new up to CCZ-equivalence. Using this approach we construct classes of nonquadratic bent Boolean and bent vectorial functions.
