In this paper, we propose an optimal beamforming scheme for secure communication in a full duplex (FD) wireless powered communication (WPC) system. In the proposed scheme, the power beacon transmits an energy signal to a source which acts as a jamming signal to an eavesdropper. We formulate an optimization problem to find an optimal beamforming for the power beacon and propose an algorithm to solve the problem. Simulation results show the secrecy performance of FD WPC system with the proposed beamforming scheme.
