On the lower bound of cost of mds matrices
Web3 de mai. de 2024 · Contribution This paper follows a list of recent papers to design new {\text {MDS}} matrices with low implementation costs. Concerning the standard XOR count metric, it yields several new matrices having lower {\text {XOR}} cost than previous results. Webon this class of matrices, and prove the a lower bound on the number of rotations for n 4 and show the tightness of the bound for n = 4. Next, by precisely characterizing the relation among sub-matrices for each possible form, we can eliminate all the other non-optimal cases. Finally, we present a direct construction of such MDS matrices, which
