无人机群的认证和切换挑战和方法
Authentication and Handover Challenges and Methods for Drone Swarms
摘要：
无人机开始用于各种目的，如边境安全，监视，货物运输，视觉展示，并且不可能用一架无人机来完成这些密集的任务。为了加快执行这些任务，采用了无人机群。根据分配的任务，群中无人机的数量可能很高。目前使用5G新无线电（NR）网络对单个无人机进行认证的解决方案需要执行两个步骤。第一步是无人机与5G核心网络之间的认证，第二步是无人机与无人机控制站之间的认证。使用当前的解决方案来认证群中的每个无人机而不引起显著的延迟是不可行的。在执行切换时，基站（BS）和用户设备（UE）之间的认证密钥必须与新BS共享。无人机群是高度移动的，并且需要从BS到新BS的几次切换。如5G NR中所解释的那样，为每个无人机共享认证密钥对于无人机群来说是不可扩展的。此外，无人机可以用作UE或无人驾驶飞行器（UxNB）上的无线电接入节点。UxNB可以在农村地区或紧急情况下向无人机群提供服务。由于无线连接性，在UxNB与新UxNB之间共享认证密钥的过程可能容易受到窃听。在这项工作中，我们提出了一种方法，其中新无人机加入群的身份验证的时间和通信次数小于5G NR。此外，针对基站是陆地或移动的场景，提出了基于组的切换解决方案，以克服5G NR中的可扩展性和延迟问题。
英文摘要：
Drones are begin used for various purposes such as border security, surveillance, cargo delivery, visual shows and it is not possible to overcome such intensive tasks with a single drone. In order to expedite performing such tasks, drone swarms are employed. The number of drones in a swarm can be high depending on the assigned duty. The current solution to authenticate a single drone using a 5G new radio (NR) network requires the execution of two steps. The first step covers the authentication between a drone and the 5G core network, and the second step is the authentication between the drone and the drone control station. It is not feasible to authenticate each drone in a swarm with the current solution without causing a significant latency. Authentication keys between a base station (BS) and a user equipment (UE) must be shared with the new BS while performing handover. The drone swarms are heavily mobile and require several handovers from BS to a new BS. Sharing authentication keys for each drone as explained in 5G NR is not scalable for the drone swarms. Also, the drones can be used as a UE or a radio access node on board unmanned aerial vehicle (UxNB). A UxNB may provide service to a drone swarm in a rural area or emergency. The number of handovers may increase and the process of sharing authentication keys between UxNB to new UxNB may be vulnerable to eavesdropping due to the wireless connectivity. In this work, we present a method where the time and the number of the communication for the authentication of a new drone joining the swarm are less than 5G NR. In addition, group-based handover solutions for the scenarios in which the base stations are terrestrial or mobile are proposed to overcome the scalability and latency issues in the 5G NR.
