Webthus reducing the implementation cost is equivalent to constructing an optimized matrix decomposition. The basic idea of this work is to find various matrix de-compositions for … WebIn this work, we identify the exact lower bound of the number of nonzero blocks for a 4 × 4 block matrix to be potentially iterative-MDS. Subsequently, we show that the theoretically lightest 4 × 4 iterative MDS block matrix (whose entries or blocks are 4 × 4 binary matrices) with minimal nonzero blocks costs at least 3 XOR gates, and a concrete example …

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
