—We study the optimum location of an eavesdropper from a secrecy capacity perspective in multiterminal networks with power control. We determine the logical location of an eavesd...
— While many protocols for sensor network security provide confidentiality for the content of messages, contextual information usually remains exposed. Such information can be c...
