Abstract |
|
In this paper, we obtain the cross-correlation spectrum of generalized bent Boolean functions in a subclass of Maiorana-
McFarland class (GMMF). An affine transformation which preserve the cross-correlation spectrum of two generalized Boolean
functions, in absolute value is also presented. A construction of generalized bent Boolean functions in (n+2) variables from four
generalized Boolean functions in n variables is presented. It is demonstrated that the direct sum of two generalized bent Boolean
functions is also generalized bent. Finally, we identify a class of affine functions, in the generalized set up, each of its function is
generalized bent. |
