On lower bounds of second-order nonlinearities of cubic bent functions constructed by concatenating Gold functions
نویسندگان
چکیده
In this paper we consider cubic bent functions obtained by Leander and McGuire (J. Comb. Th. Series A, 116 (2009) 960-970) which are concatenations of quadratic Gold functions. A lower bound of second-order nonlinearities of these functions is obtained. This bound is compared with the lower bounds of second-order nonlinearities obtained for functions belonging to some other classes of functions which are recently studied.

متن کاملOn lower bounds on second-order nonliearities of bent functions obtained by using Niho power functions
In this paper we find a lower bound of the second-order nonlinearities of Boolean bent functions of the form f(x) = Tr 1 (α1x d1 + α2x 2), where d1 and d2 are Niho exponents. A lower bound of the second-order nonlinearities of these Boolean functions can also be obtained by using a result proved by Li, Hu and Gao (eprint.iacr.org/2010 /009.pdf). It is demonstrated that for large values of n the...
متن کاملOn second order nonlinearities of cubic monomial Boolean functions
We study cubic monomial Boolean functions of the form Trn 1 (μx 2i+2j+1) where μ ∈ F2n . We prove that the functions of this form do not have any affine derivative if n 6= i+ j or n 6= 2i− j. Lower bounds on the second order nonlinearities of these functions are derived.
متن کاملSecond Order Nonlinearities of Some Classes of Cubic Boolean Functions Based on Secondary Constructions
The higher order nonlinearity of a Boolean function is a cryptographic criterion, which play a role against attacks on stream and block ciphers. Also it play a role in coding theory, since it is related to the covering radii of Reed-Muller codes. In this paper, we study the lower bounds of second-order nonlinearities of a class of cubic Boolean functions of the form with and ∈ ′ and some classe...
متن کاملOn the lower bounds of the second order nonlinearities of some Boolean functions
The r-th order nonlinearity of a Boolean function is an important cryptographic criterion in analyzing the security of stream as well as block ciphers. It is also important in coding theory as it is related to the covering radius of the Reed-Muller code R(r, n). In this paper we deduce the lower bounds of the second order nonlinearity of the following two types of Boolean functions: 1. fλ(x) = ...
