We consider i) the overhead minimization of maximum-distance separable (MDS) storage codes for the repair of a single failed node and ii) the total secure degrees-of-freedom (S-DoF) maximization in a multiple-access compound wiretap channel. We show that the two problems are connected. Specifically, the overhead minimization for a single node failure of an optimal MDS code, i.e. one that can achieve the information theoretic overhead minimum, is equivalent to maximizing the S-DoF in a multiple… CONTINUE READING
