This paper investigates the degradation properties of Boolean functions from the aspects of the distributions of dierences and linear masks, and shows two characterizations of the degraded Boolean fu...
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...
A method for obtaining lower bounds on the higher order nonlinearity of Boolean function

2014/3/12
Obtainment of exact value or high lower bound on the $r$-th order nonlinearity of Boolean function is a very complicated problem (especial if $r > 1$). In a number of papers lower bounds on the $r$-th...

2012/3/23
In this paper, We propose a class of 2k-variable Boolean functions, which have optimal algebraic degree, high nonlinearity, and are 1-resilient. These functions have optimal algebraic immunity when k ...
The Good lower bound of Second-order nonlinearity of a class of Boolean function
Boolean function Higher-order derivatives Second-order nonlinearit Walsh-spectrum

this paper we find the lower bound of second-order nonlinearity of Boolean function $f_{\lambda}(x) = Tr_{1}^{n}(\lambda x^{p})$ with $p = 2^{2r} + 2^{r} + 1$, $\lambda \in \mathbb{F}_{2^{r}}^{*}$ and...
Efficient Approximation of Higher Order Boolean function in a Low Order Function
Efficient Approximation Higher Order Boolean function Low Order Function

2009/7/14
A few of non-linear approximation methods for Boolean functions
have been developed but they are not of practical application. However,
if a low order Boolean function can be found that can nearly a...

This paper proposed a first order recursive construction of
Boolean function with optimum algebraic immunity. We also show that
the Boolean functions are balanced and have good algebraic degrees.

This paper proposed an improved construction of even-variable
Boolean function with optimum algebraic degree. Compared with those
in [1], our Boolean functions are more balance. Specially, for k=2t+...

Abstract: Because of the algebraic attacks, a high algebraic immunity is
now an important criteria for Boolean...

2008/10/23
Low degree annihilators for Boolean functions are of great interest in
cryptology because of algebraic attacks on LFSR-based stream ciphers. Several
polynomial algorithms for construction of low deg...
Balanced Boolean Function on 13-variables having Nonlinearity strictly greater than the Bent Concatenation Bound

2008/5/30
Very recently, Kavut and Yucel identified 9-variable Boolean functions having
nonlinearity 242, which is currently the best known. However, any of these functions
do not contain any zero in the Wals...
