Parker considered a new type of discrete Fourier transform, called nega-Hadamard
transform. We prove several results regarding its behavior on combinations of Boolean …

Bent and generalized bent Boolean functions

P Stănică, T Martinsen, S Gangopadhyay… - Designs, codes and …, 2013 - Springer
In this paper, we investigate the properties of generalized bent functions defined on Z _2^ n

Characterization of negabent functions and construction of bent-negabent functions with maximum algebraic degree

W Su, A Pott, X Tang - IEEE transactions on information theory, 2013 - ieeexplore.ieee.org
We present necessary and sufficient conditions for a Boolean function to be a negabent
function for both an even and an odd number of variables, which demonstrates the …

Constructions of bent—negabent functions and their relation to the completed Maiorana—McFarland class

F Zhang, Y Wei, E Pasalic - IEEE Transactions on Information …, 2015 - ieeexplore.ieee.org
The problem of constructing bent-negabent functions that do not belong to the completed
Maiorana-McFarland class emerges implicitly through a series of construction methods …

Generalized Walsh transforms of symmetric and rotation symmetric Boolean functions are linear recurrent

FN Castro, LA Medina, P Stănică - Applicable Algebra in Engineering …, 2018 - Springer
Exponential sums of symmetric Boolean functions are linear recurrent with integer
coefficients. This was first established by Cai, Green and Thierauf in the mid nineties …

Several secondary methods for constructing bent–negabent functions

F Guo, Z Wang, G Gong - Designs, Codes and Cryptography, 2023 - Springer
In this paper, we present three secondary methods for constructing bent–negabent functions
under the frameworks of the indirect sum construction (proposed by Carlet in 2004), the …

Characterizing negabent Boolean functions over finite fields

S Sarkar - International Conference on Sequences and Their …, 2012 - Springer
We consider negabent Boolean functions that have Trace representation. To the best of our
knowledge, this is the first ever work on negabent functions with such representation. We …

Walsh spectrum and Nega spectrum of complementary arrays

J Chai, Z Wang, E Xue - Designs, Codes and Cryptography, 2021 - Springer
It has been shown that all the known binary Golay complementary sequences of length 2^ m
2 m can be obtained by a single binary Golay complementary array of dimension m and size …

Further results on constructions of generalized bent Boolean functions.

F Zhang, S **a, P Stanica, Y Zhou - Sci. China Inf. Sci., 2016 - apps.dtic.mil
Boolean bent functions were introduced by Rothaus in 1976 as an interesting combinatorial
object with the important property of having optimal nonlinearity 1. Since bent functions have …

On Generalized Nega-Hadamard Transform and Nega-crosscorrelation

D Sharma, M Ahmad Dar - Cryptography and Communications, 2024 - Springer
In the construction of cryptosystems, we need functions with some cryptographically
significant properties. It is known that the Global Avalanche Characteristic (GAC) is one of …
