Ting Li and Jian Bai and Yao sun and Dingkang Wang and Dongdai Lin

Abstract: MDS matrices are important parts for block ciphers. We searched the $4\times 4$ MDS matrices over GL(4, $\mathbb{F}_2$), and found the lightest MDS matrices only have 10 XOR operations. Besides, all these lightest MDS matrices can be classified to 3 classes.
