Özet

In this study, the authors generalise Hadamard matrix over F2 m and propose a new form of Hadamard matrix, which they call generalised Hadamard (GHadamard) matrix. Then, they focus on generating lightweight (involutory) maximum distance separable (MDS) matrices. They also extend this idea to any k × k matrix form, where k is not necessarily a power of 2. The new matrix form, GHadamard matrix, is used to generate new 4 × 4 involutory MDS matrices over F2 4 and F2 8, and 8 × 8 involutory/ non-involutory MDS matrices over F2 4 by considering the minimum exclusive OR (XOR) count, which is a metric defined to estimate the hardware implementation cost. In this context, they improve the best-known results of XOR counts for 8 × 8 involutory/non-involutory MDS matrices over F2 4
