The secrecy capacity of a network, for a given collection of permissible wiretap sets, is the maximum rate of communication such that observing links in any permissible wiretap set reveal no information about the message. This paper considers secure network coding with nonuniform or restricted wiretap sets, for example, networks with unequal link capacities where a wiretapper can wiretap any subset...
We address secure network coding over networks with unequal link capacities in the presence of a wiretapper who has only access to a restricted number of k links in the network. Previous results show that for the case of equal link capacities and unrestricted wiretapping sets, the secrecy capacity is given by the cut-set bound, whether or not the location of the wiretapped links is known. The cut-set...
This paper considers secure network coding over networks with restricted wiretapping sets and unequal link capacities in the presence of a wiretapper that can wiretap any subset of k links. In particular, we consider networks with point-to-point erasure channels. Existing results for wireline networks show that for the case of both unrestricted wiretapping sets and equal (unit) link capacities, the...
