Quasi-twisted codes as contractions of quasi-cyclic codes Özkaya, Buket; Özbudak, Ferruh (2023-10-01)
Classification of some quadrinomials over finite fields of odd characteristic Özbudak, Ferruh; Gulmez Temur, B. or Temur (2023-03-01) In this paper, we completely determine all necessary and sufficient conditions such that the polynomialf(x)=x3+axq+2+bx2q+1+cx3q" role="presentation" style="margin: 0px; padding: 0px; display: inline-block; line-height: no...
Sonlu cisimler üzerindeki x^k-cx-d polinomlarının iki uygulaması üzerine ve daha fazlası İrimağzı, Canberk; Özbudak, Ferruh (Springer, Cham, 2023-1-11) For integers k∈[2,q−2] coprime to q−1 , we first bound the number of zeroes of the family of polynomials xk−cx−d∈Fq[x] where q=2n such that q−1 is a prime or q=3n such that (q−1)/2 is a prime. This gives us bounds on...
Boomerang uniformity of power permutations and algebraic curves over F2n Mesnager, Sihem; Özbudak, Ferruh (2023-01-01) We obtain the Boomerang Connectivity Table of power permutations F(x)=x2m-1 of F2n with m ∈ {3, n-1/2, n+1/2, n-2}. In particular, we obtain the Boomerang uniformity and the Boomerang uniformity set of F(x) at b∈F2n\F2. Mo...
On two applications of polynomials x^k-cx-d over finite fields and more İrimağzı, Canberk; Özbudak, Ferruh (Springer, Cham, 2023-01-01) For integers k∈[2,q−2] coprime to q−1 , we first bound the number of zeroes of the family of polynomials xk−cx−d∈Fq[x] where q=2n such that q−1 is a prime or q=3n such that (q−1)/2 is a prime. This gives us bounds on...
Complete characterization of some permutation polynomials of the form xr(1+axs1(q-1)+bxs2(q-1)) over Fq2 Özbudak, Ferruh; Temür, Burcu Gülmez (2023-01-01) We completely characterize all permutation trinomials of the form f(x) = x3(1 + axq-1+ bx2(q-1)) over Fq2, where a,b∈Fq∗ and all permutation trinomials of the form f(x) = x3(1 + bx2(q-1)+ cx3(q-1)) over Fq2, where b,c∈Fq∗ ...
On subfield subcodes obtained from restricted evaluation codes Güneri, Cem; Özbudak, Ferruh; Sayıcı, Selcen (2023-01-01) Galindo et al. introduced a class of codes which are obtained by evaluation of polynomials at the roots of a trace map (Galindo et al. in IEEE Trans Inform Theory 65: 2593–2602, 2019). Via subfield subcodes, this construct...
The c-differential uniformity of the perturbed inverse function via a trace function Tr(x2x+1) Kaytancı, Kübra; Özbudak, Ferruh (2023-01-01) Differential uniformity is one of the most crucial concepts in cryptography. Recently Ellingsen et al. (IEEE Trans Inf Theory 66:5781–5789, 2020) introduced a new concept, the c-Difference Distribution Table and the c-diff...
Optimal Binary Linear Complementary Pairs of Codes Choi, Whan-Hyuk; GÜNERİ, CEM; Kim, Jon-Lark; Özbudak, Ferruh (2022-11-01) A pair of linear codes (C, D) of length n over F-q is called a linear complementary pair (LCP) if their direct sum yields the full space F-q(n). By a result of Carlet et al. (2019), the best security parameters of binary L...
Additive cyclic complementary dual codes over F4 Shi, Minjia; Liu, Na; Özbudak, Ferruh; Solé, Patrick (2022-10-01) © 2022 Elsevier Inc.An additive cyclic code of length n over F4 can be defined equivalently as an F2[x]/〈xn+1〉-submodule of F4[x]/〈xn+1〉. In this paper we study additive cyclic and complementary dual codes of odd length ov...
