Web1 de jul. de 2024 · Hence, we construct 32×32 matrices with the lightweight 16×16 matrices that we found. In this way, we obtain two classes of 4×4 involutory MDS matrices whose entries are 8×8 binary... Webthe implementation cost of 4 4 MDS matrices with 4-bit input words is 72 XORs. Zhang et al. in [23] provide cyclic 4 4 MDS matrices with 4-bit input words and 12 XORs for entries which overall requires 4 12 + 12 = 60 XORs for implementation. Recently, Zhou et al.
