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 Webnamely cyclic MDS matrices and propose new MDS matrices of this type. The presented matrices have lower implementation costs compared to what is presented up to now. In [10,15,16] diffusion layers in the form of a matrix power are examined. In this paper, we study decomposition of matrices from another viewpoint: we consider the product of ...

WebThe construction of recursive MDS matrices also has a relation with coding the-ory. It is shown that recursive MDS matrices can be constructed from Gabidulin codes [4], and also can be obtained directly from shortened MDS cyclic codes [2]. However, a recursive MDS matrix may leads to high latency since it has to run several rounds to get outputs.
