On the lower bound of cost of mds matrices
Web6 de out. de 2024 · Many block ciphers and hash functions use MDS matrices because of their optimal branch number. On the other hand, MDS matrices generally have a high implementation cost, which makes them unsuitable for lightweight cryptographic primitives. Web13 de nov. de 2024 · One promising way of realizing low-cost MDS matrices is based on the iterative construction: a low-cost matrix becomes MDS after rising it to a certain power. To be more specific, if A t is MDS, then one can implement A instead of A t to achieve the MDS property at the expense of an increased latency with t clock cycles.
