Web1 de abr. de 2024 · Over the last decade, the main concern regarding the construction of MDS matrices has been the determination of small-scale MDS matrices to reduce the implementation cost of lightweight block ciphers. WebThe construction of recursive MDS matrices also has a relation with coding the-ory. It is shown that recursive MDS matrices can be constructed from Gabidulin codes [4], and also can be obtained directly from shortened MDS cyclic codes [2]. However, a recursive MDS matrix may leads to high latency since it has to run several rounds to get outputs.
