Proposing secure and efficient MDS matrices to improve the diffusion layer of the AES block cipher

In this paper, we will propose a method of finding secure MDS matrices that are efficient for execution. By the proposed method, we will produce such MDS matrices of sizes 4, 8, and 16 that can be used to improve the diffusion layer of the AES block cipher or used for other SPN block ciphers later.
