Relation between o-equivalence and EA-equivalence for Niho bent functions
Bent function Boolean function EA-equivalence
font style='font-size:12px;'>
2019/7/15
Boolean functions, and bent functions in particular, are considered up to so-called EA-equivalence, which is the most general known equivalence relation preserving bentness of functions. However, for ...
Composition of Boolean Functions: An Application to the Secondary Constructions of Bent Functions

Bent functions are optimal combinatorial objects and have been attracted their research for four decades. Secondary constructions play a central role in constructing bent functions since a complete cl...

We present a construction of bent function fa,Sfa,S with n=2mn=2m variables for any nonzero vector a∈Fm2a∈F2m and subset SS of Fm2F2m satisfying a+S=Sa+S=S. We give the simple expression of the dual b...
The graph of minimal distances of bent functions and its properties
Boolean functions bent functions the minimal distance
font style='font-size:12px;'>
2016/1/27
A notion of the graph of minimal distances of bent functions is introduced. It is an
undirected graph (V , E) where V is the set of all bent functions in 2k variables and (f, g) ∈ E
if the Hamming d...
When a Boolean Function can be Expressed as the Sum of two Bent Functions
Bent functions Sum of bent functions Maiorana-MacFarland bent function
font style='font-size:12px;'>
2016/1/26
In this paper we study the problem that when a Boolean function can
be represented as the sum of two bent functions. This problem was recently
presented by N. Tokareva in studying the number of bent...
Constructing hyper-bent functions from Boolean functions with the Walsh spectrum taking the same value twice
Bent function hyper-bent function Dillon exponents
font style='font-size:12px;'>
2016/1/8
Hyper-bent functions as a subclass of bent functions attract much
interest and it is elusive to completely characterize hyper-bent functions. Most
of known hyper-bent functions are Boolean functions...
On the Primary Constructions of Vectorial Boolean Bent Functions
Bent functions vetorial Boolean functions perfect nonlinear functions
font style='font-size:12px;'>
2016/1/4
Vectorial Boolean bent functions, which possess the maximal nonlinearity and the minimum differential uniformity, contribute to optimum resistance against linear cryptanalysis and differential cryptan...
More PS and H-like bent functions
secret-key cryptography boolean functions
font style='font-size:12px;'>
2016/1/3
Two general classes (constructions) of bent functions are derived from the notion of spread. The first class, PS, gives a useful framework for designing bent functions which are constant (except maybe...
On the Systematic Constructions of Rotation Symmetric Bent Functions with Any Possible Algebraic Degrees
Orbit rotation symmetric function Walsh transform
font style='font-size:12px;'>
2015/12/30
In the literature, few constructions of n-variable rotation symmetric bent functions have been presented,
which either have restriction on n or have algebraic degree no more than 4. In this paper, fo...
An analysis of the $C$ class of bent functions
Boolean functions bent functions permutation polynomials
font style='font-size:12px;'>
2015/12/29
Two (so-called C, D) classes of permutation-based bent Boolean functions were introduced
by Carlet two decades ago, but without specifying some explicit construction methods
for their construction (...
Bent and Semi-bent Functions via Linear Translators
Boolean functions Bent functions Semi-bent functions
font style='font-size:12px;'>
2015/12/23
The paper is dealing with two important subclasses of plateaued functions: bent
and semi-bent functions. In the first part of the paper, we construct mainly bent and semi-bent
functions in the Maior...
A note on constructions of bent functions from involutions

2015/12/22
Bent functions are maximally nonlinear Boolean functions. They are important
functions introduced by Rothaus and studied firstly by Dillon and next by many researchers
for four decades. Since the co...

2015/12/21
We contribute to the knowledge of linear codes with few weights from special polynomials
and functions. Substantial efforts (especially due to C. Ding) have been directed
towards their study in the ...
