Aiming at the problem of limited available energy and serious information leakage risks faced by the relay nodes in the multi-antenna relay system, a physical layer secure transmission scheme of joint relay beamforming and multi-antenna friendly jammer cooperative jamming based on energy harvesting technology is proposed. Firstly, a multi-antenna cooperative relay network based on the amplify-and-forward (AF) mode is constructed. Secondly, the relay nodes and friendly jammers perform energy harvesting and confidentiality signal transmission based on the time switching (TS) strategy. Then, with the goal of the system secrecy rate maximization（SRM），the optimal relay signal transmission beamforming matrix，artificial noise（AN） covariance and time switching coefficient are jointly designed under the condition of meeting the energy harvesting constraints of the relay and the friendly jammers. However, due to conditional constraints, the SRM problem is a non-convex. Therefore, a Bi-level optimization algorithm is designed to obtain the optimal solution by combining semi-definite relaxation（SDR） technology and Lagrange duality theory, and in order to reduce the complexity and compare the performance of the proposed scheme, a suboptimal transmission scheme based on zero-forcing precoding is given. Finally, the simulation results show that the proposed scheme can significantly improve the security performance of the system and has a certain anti-eavesdropping attack capability.
