On the lower bound of cost of mds matrices
Webtings. For example, for linear computations, i.e., matrix-matrix or matrix-vector multiplications, [5], [6] use Freivalds’ algorithm to detect Byzantine errors with high probability and exclude them in further processing. For polynomial computations, [7] uses properties of error-correcting codes to correct the erroneous results. Other Webthe implementation cost of 4 4 MDS matrices with 4-bit input words is 72 XORs. Zhang et al. in [23] provide cyclic 4 4 MDS matrices with 4-bit input words and 12 XORs for entries which overall requires 4 12 + 12 = 60 XORs for implementation. Recently, Zhou et al. [20] pro-posed two kinds of lightweight 4 4 MDS matrices over

We show that for circulant MDS matrices with the first row’s entries are [ I , I , A , B ], the fewest sum of XORs of A and B … 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.
