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 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 WebWe prove a lower bound on for the case of d= (n 1). This bound holds for any w( n 1) and is shown to be tight, again by comparing with recent code constructions in the literature. Also provided, are bounds for the case d<(n 1).

"WebMDS matrices are derived from MDS codes. An [n, k, d] code C is MDS if it meets the singleton bound d = n − k + 1. MDS matrices have the maximum differential and linear branch number (k + 1 for k × k MDS matrices) [15]. Some important properties of MDS matrices can be given as follows: i.
