Center hyperedge (induced by source paper "security for wiretap networks via rank metric codes"):
  Abstract: The problem of securing a network coding communication system against a wiretapper adversary is considered. The network implements linear network coding to deliver n packets from source to each receiver, and the wiretapper can eavesdrop on mu arbitrarily chosen links. A coding scheme is proposed that can achieve the maximum possible rate of k = n - mu packets that are information-theoretically secure from the adversary. A distinctive feature of our scheme is that it is universal: it can be applied on top of any communication network without requiring knowledge of or any modifications on the underlying network code. In fact, even a randomized network code can be used. Our approach is based on Rouayheb-Soljaninpsilas formulation of a wiretap network as a generalization of the Ozarow-Wyner wiretap channel of type II. Essentially, the linear MDS code in Ozarow-Wynerpsilas coset coding scheme is replaced by a maximum-rank-distance code over an extension of the field in which linear network coding operations are performed.
