Simultaneous wireless information and power transfer (SWIPT) has drawn significant research interest in recent years.In this paper, we investigate the information theoretic secrecy of a SWIPT system under Weibull fading channel.To be specific, we analyze the information security in the presence of an energy harvesting and information decoding eavesdropper.All links are subjected to Weibull fading which is more complex than traditional Rayleigh fading.Moreover, we derive closed-form expressions for the probability of strictly positive secrecy capacity and the ergodic secrecy capacity.We evaluate the effect of Weibull shape parameter and power splitting factor on the secrecy performance of SWIPT system.Numerical and simulation results are provided to demonstrate that our findings are instantly applicable on the design of wireless power networks.
