全双工辅助的无人机上行通信抗窃听物理层安全技术研究
Research on full-duplex assisted physical layer security technology for anti-eavesdropping of UAV uplink communication
摘要
Abstract
In view of the eavesdropping attacks on the uplink of UAVs,a secure transmission strategy of full-duplex cooperative interference is proposed.In the scheme,the information differences obtained by the transmitter and receiver at each stage of data transmission and the prior information features mastered are utilized to inject artificial noise signals into the signal to be transmitted,so as to make the eavesdropping link form an interference-limited system.Under constraints such as transmission power and UAV mobility,a joint optimization problem that maximizes the system's secrecy rate is constructed.On the basis of the alternating optimization method and continuous convex approximation technology,the non-convex problem is transformed into two sub-problems,and an iterative optimization algorithm is designed to effectively solve the joint optimization problem.Simulation results show that the proposed secure transmission scheme can significantly improve the secrecy rate of the full-duplex UAV relay communication system and show better performance in comparison with the other reference schemes.关键词
