无人机(Unmanned Aerial Vehicle,UAV)通信的发展面临着安全性和效率的双重挑战。本文探讨了当前无人机通信面临的一个具有未来性且重要的问题:如何在保持通信保密性的同时,使无人机尽可能节能?为了解决这个问题,提出了一种针对先进的双无人机安全通信系统的保密能效最大化(Secrecy Energy Efficiency Maximization,SEEM)解决方案。在这样的系统中,源无人机在干扰器无人机的协助下确保信息的安全传输。为了在安全性和效率之间建立最佳平衡,寻求最大化双无人机安全通信的保密能效(Secrecy Energy Efficiency,SEE)。由于该问题的非凸性和窃听者位置不精确,因此很难最优地解决这个问题。基于逐次凸近似(Successive Convex Approximation,SCA)和S程序技术,SEEM解决方案旨在优化此情况下源无人机和干扰器无人机的轨迹。模拟实验结果表明,对于双无人机启用的安全通信系统,所提出的解决方案可以建立比其他基准解决方案更高的SEE。因此,所提出的解决方案可以同时关注双无人机启用的安全通信的传输隐蔽性和能源效率。

The development of unmanned aerial vehicle (UAV) enabled communication faces challenges of both security and efficiency. A futuristic yet important problem faced by the current UAV-enabled communication was explored how could we make UAVs as energy efficient as possible while maintaining the communication secrecy? To solve this problem, a secrecy energy efficiency maximization (SEEM) solution for advanced dual-UAV-enabled secure communication systems was proposed. In such systems, a source UAV ensured secured information transmission with the assistance of a jammer UAV. In order to establish the optimal trade-off between security and efficiency, maximal secrecy energy efficiency (SEE) for dual-UAV enabled secure communications was seeked. Solving the issue optimally was challenging because of its non-convexity and imprecise locations of eavesdroppers. Based on the successive convex approximation (SCA) and S-procedure techniques, the SEEM solution was designed for optimizing the trajectory of source and jammer UAVs in this situation. The simulation results demonstrated that the proposed solution could establish a substantially greater SEE than other benchmark solutions for dual-UAV-enabled secure communication systems. Consequently, the proposed solution could focus on both transmission covertness and energy efficiency for dual-UAV-enabled secure communications.
