Efficient methods to generate cryptographically significant binary diffusion layers
Akleylek, Sedat; Rijmen, Vincent; Sakalli, Muharrem Tolga; Ozturk, Emir (Inst Engineering Technology-Iet, 2017)In this study, the authors propose new methods using a divide-and-conquer strategy to generate n x n binary matrices ( for composite n) with a high/maximum branch number and the same Hamming weight in each row and column. ... -
Generalisation of Hadamard matrix to generate involutory MDS matrices for lightweight cryptography
Pehlivanoglu, Meltem Kurt; Sakalli, Muharrem Tolga; Akleylek, Sedat; Duru, Nevcihan; Rijmen, Vincent (Inst Engineering Technology-Iet, 2018)In this study, the authors generalise Hadamard matrix over F-2m and propose a new form of Hadamard matrix, which they call generalised Hadamard (GHadamard) matrix. Then, they focus on generating lightweight (involutory) ... -
A new matrix form to generate all 3 x 3 involutory MDS matrices over F-2(m)
Guzel, Gulsum Gozde; Sakalli, Muharrem Tolga; Akleylek, Sedat; Rijmen, Vincent; Cengellenmis, Yasemin (Elsevier Science Bv, 2019)In this paper, we propose a new matrix form to generate all 3 x 3 involutory and MDS matrices over F-2(m) and prove that the number of all 3 x 3 involutory and MDS matrices over F-2(m) is (2(m) - 1)(2) . (2(m) - 2) . (2(m) ... -
On the automorphisms and isomorphisms of MDS matrices and their efficient implementations
Sakalli, Muharrem Tolga; Akleylek, Sedat; Akkanat, Kemal; Rijmen, Vincent (Tubitak Scientific & Technical Research Council Turkey, 2020)In this paper, we explicitly define the automorphisms of MDS matrices over the same binary extension field. By extending this idea, we present the isomorphisms between MDS matrices over F-2m and MDS matrices over F-2mt, ...
