Abstract

Abstract

To solve the problems of security threats and energy constrained in wireless networks, this paper studies secure communication of energy harvesting Gaussian wiretap channel based on Save-then-Transmit (ST) protocol. Firstly, the optimization of the system secrecy rate is studied. Next, to further improve the system secrecy rate, a Cooperative Jamming (CJ) scheme is given. Besides, the sufficient and necessary conditions for this scheme to achieve a higher secrecy rate are discussed. Then, an iterative optimization algorithm of the secrecy rate in this scheme is proposed. Finally, a low complexity selection scheme for single helper is given. Simulation results show that, the first optimization scheme obviously improves the system secrecy rate. The second cooperative jamming scheme can further enhance the system secrecy rate and has fast convergence rate. When the original energy harvesting Gaussian wiretap channel can not operate secure communication, the cooperative jamming scheme can achieve secure transmission under certain conditions.
