Abstract
A novel approach for ensuring confidential communications over infrastructure-based wireless networks is proposed and analyzed from an information-theoretic standpoint. The considered techniques leverage the finite-capacity backbone connecting the base stations and the possibility to schedule uplink/downlink transmissions in order to create intentional interference. Two different methods are studied, one based on source coding and one on channel coding arguments, and corresponding rates achievable with perfect secrecy are derived.
