While cognitive radio enables spectrum-efficient wire-less communication,radio frequency(RF)energy har-vesting from ambient interference is an enabler for energy-efficient wireless communication.In this paper,we investigate the physical layer security issues for an underlay cognitive radio system,which consist of an information transmitter,a desired information receiver,and an energy-harvesting(EH)receiver,the EH receiv-er performs simultaneous wireless information and power transfer(SWIPT)based on a power splitting re-ceiver architecture,which is also a potential eaves-dropper and has the capability to overhear the confi-dential messages between source node and the special information receiver.
