ABSTRACT

Thanks to the rapidly developing technology, unmanned aerial vehicles (UAVs) are able to complete a number of tasks in cooperation with each other without need for human intervention. In recent years, UAVs, which are widely utilized in military missions, have begun to be deployed in civilian applications and mostly for commercial purposes. With their growing numbers and range of applications, UAVs are becoming more and more popular; on the other hand, they are also the target of various threats which can exploit various vulnerabilities of UAV systems in order to cause destructive effects. It is therefore critical that security is ensured for UAVs and the networks that provide communication between UAVs. This survey seeks to provide a comprehensive perspective on security within the domain of UAVs and Flying Ad Hoc Networks (FANETs). Our approach incorporates attack surface analysis and aligns it with the identification of potential threats. Additionally, we discuss countermeasures proposed in the existing literature in two categories: preventive and detection strategies. Our primary focus centers on the security challenges inherent to FANETs, acknowledging their susceptibility to insider threats due to their decentralized and dynamic nature. To provide a deeper understanding of these challenges, we simulate and analyze four distinct routing attacks on FANETs, using realistic parameters to evaluate their impact. Hence, this study transcends a standard review by integrating an attack analysis based on extensive simulations. Finally, we rigorously examine open issues, and propose research directions to guide future endeavors in this field.

主要发现

  • 仿真结果表明,黑洞和sinkhole攻击在FANET中导致分组交付比最严重下降,并显著增加端到端延迟。
  • 下垂和泛洪攻击严重破坏网络稳定性,其中泛洪攻击导致高控制开销并降低吞吐量。
  • 预防性机制(如加密认证和安全路由协议)在缓解特定攻击类型方面表现有效,但在高移动性环境中面临可扩展性挑战。
  • 基于机器学习的异常检测检测型方法在模拟FANET场景中表现出识别恶意行为的潜力,且误报率较低。
  • 利用数字孪生对无人机系统建模,可实现早期故障检测并增强态势感知能力,尤其在连接中断期间效果显著。
  • 现有标准(如JAUS、UASSC和PODIUM)对异构无人机系统支持有限,且缺乏全面的安全集成,凸显了关键的研究空白。
