On cross-correlation spectrum of generalized bent functions in generalized Maiorana-McFarland class
نویسنده
چکیده
In this paper, we obtain the cross-correlation spectrum of generalized bent Boolean functions in a subclass of MaioranaMcFarland 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.

متن کاملA Maiorana-McFarland Construction of a GBF on Galois ring
Bent functions shows some vital properties among all combinatorial objects. Its links in combinatorics, cryptography and coding theory attract the scientific community to construct new class of bent functions. Since the entire characterisation of bent functions is still unexplored but several construction on different algebraic structure is in progress. In this paper we proposed a generalized M...

Kumar et al.(1985) have extended the notion of classical bent Boolean functions in the generalized setup on Zq . They have provided an analogue of classical Maiorana-McFarland type bent functions. In this paper, we study the crosscorrelation of a subclass of such generalized MaioranaMcFarland (GMMF) type bent functions. We provide a construction of quaternary (q = 4) bent functions on n + 1 var...
متن کاملGeneralized bent functions - sufficient conditions and related constructions
The necessary and sufficient conditions for a class of functions f : Z 2 → Zq, where q ≥ 2 is an even positive integer, have been recently identified for q = 4 and q = 8. In this article we give an alternative characterization of the generalized Walsh-Hadamard transform in terms of the Walsh spectra of the component Boolean functions of f , which then allows us to derive sufficient conditions t...
