Addressing the issue of weak confidentiality performance in unmanned aerial vehicle(UAV)relay communication systems due to energy shortages,an optimization scheme for enhan-cing the confidentiality performance of high-efficiency UAV multi-level communication systems is proposed.By applying energy harvesting technology to the UAV relay system and optimizing the energy allocation strategy,the RF energy collected by the UAV is efficiently utilized,thereby en-hancing the confidentiality of the UAV relay communication system.A comparison of the confi-dentiality performance between the unoptimized and optimized UAV relay systems is conducted to verify the effectiveness of the proposed scheme.Simulation results demonstrate that the opti-mized system outperforms the unoptimized system in terms of confidentiality performance.Under the same transmission conditions,the proposed scheme can improve the confidentiality perform-ance of the UAV relay communication system.
