We study multidimensional meet-in-the-middle attacks onthe KATAN block cipher family. Several improvements to the basicattacks are explained. The most noteworthy of these is the technique ofguessing only non-linearly involved key bits, which reduces the searchspace by a significant factor. The optimization decreases the complexityof multidimensional meet-in-the-middle attacks, allowing more rounds ofKATAN to be efficiently attacked than previously reported.
