In this paper, we propose a self-interference assisted cooperative jamming scheme to guarantee the security of wireless communication. Different from the traditional cooperative jamming schemes where artificial noise is designed in one phase (or one time slot), we design artificial noise in multiple phases. Moreover, we innovatively introduce carefully designed self-interference in the transmitted signals, which not only guarantees transmission efficiency, but also further enhances security. We first analyze the number of eavesdropping antennas on the security performance and then obtain the secrecy rate. Finally, simulation results corroborate our theoretical analysis.
