Title: Optimization of transmit signals to interfere eavesdropping in a wireless LAN
Abstract: We consider physical-layer security of a wireless LAN where multiple receivers collude to eavesdrop the information from the base station to the intended receiver. To enhance the physical-layer security, we design the interference signals to combat the eavesdropping. Our design problems are resolved using semidefinite relaxation problems, which can be numerically solved efficiently by the existing convex optimization solvers. Simulation results are provided to demonstrate the efficiency of the proposed designs.
