Abstract :
An information identity is proven, equating the secrecy capacity of the multiterminal secret key agreement problem and the throughput of certain undirected network. As a consequence, network coding can be used for secret key agreement while secrecy capacity characterizes the network throughput. A meaningful notion of mutual dependence is established with the combinatorial interpretation of partition connectivity.
