On Second-order Nonlinearities of Some D 0 Type Bent Functions

Sugata Gangopadhyay; Brajesh Kumar Singh

In this paper we study the lower bounds of second-order nonlinearities of bent functions in the class D0 constructed by modifying certain cubic Maiorana-McFarland (MMF) type bent functions. We also obtain improvements on existing results on second-order nonlinearities of some cubic MMF type bent functions having no affine derivative.
