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 reveals no information about the message. This paper considers secure network coding with non-uniform or restricted wiretap sets, for example, networks with unequal link capacities where a wire-tapper can wiretap any subset of k links, or networks where only a subset of links can be wiretapped.
