Secondary constructions on generalized bent functions

Brajesh Kumar Singh

Abstract: In this paper, we construct generalized bent Boolean functions in $n+ 2$ variables from $4$ generalized Boolean functions in $n$ variables. We also show that the direct sum of two generalized bent Boolean functions is generalized bent. Finally, we identify a set of affine functions in which every function is generalized bent.

Category / Keywords: secret-key cryptography / Generalized Boolean functions; generalized bent functions; Walsh--Hadamard transform.
