Graph classification for quadratic bent functions in 6 variables

Abstract:
The classification problem for bent functions in few variables is considered. The classification for graphs of quadratic bent functions in 6 variables is given. The analysis of resulting graphs is made and new iterative constructions of bent functions are found.
Tab. 2, bibliogr. 8.

Keywords: boolean function, nonlinearity, bent function, algebraical normal form (ANF), graph equivalence, iterative construction.
