Abstract
Systems and methods of friendly jamming for securing wireless communications at the physical layer are presented. Under the assumption of exact knowledge of the eavesdropping channel, a resource-efficient distributed approach is used to improve the secrecy sum-rate of a multi-link network with one or more eavesdroppers while satisfying an information-rate constraint for all links. A method based on mixed strategic games can offer robust solutions to the distributed secrecy sum-rate maximization. In addition, a block fading broadcast channel with a multi-antenna transmitter, sending two or more independent confidential data streams to two or more respective users in the presence of a passive eavesdropper is considered. Lastly, a per-link strategy is considered and an optimization problem is formulated, which aims at jointly optimizing the power allocation and placement of the friendly jamming devices for a given link under secrecy constraints.
