摘要:

弹性和鲁棒的定位,导航和定时(PNT)系统是自动驾驶车辆(AV)导航的必要条件。全球导航卫星系统提供基于卫星的PNT服务。然而,假卫星可以调节真实的GNSS信号,并且可以向AV发送错误的位置信息。因此,GNSS必须具有对与PNT接收器相关的欺骗攻击进行实时检测和反馈校正的能力,从而如果最终用户(在这种情况下为自主车辆)陷入任何妥协,则其将帮助最终用户安全地导航。本文旨在使用低成本的车载传感器数据开发一种基于深度强化学习(RL)的逐向欺骗攻击检测。我们利用本田驾驶数据集创建攻击和非攻击数据集,开发深度RL模型,并评估基于RL的攻击检测模型的性能。我们发现,RL模型的准确率范围从99.99%到100%,召回值为100%。然而,精确度范围为93.44%至100%,f1评分范围为96.61%至100%。总的来说,分析表明,RL模型是有效的轮流欺骗攻击检测。

英文摘要:

A resilient and robust positioning, navigation, and timing (PNT) system is a necessity for the navigation of autonomous vehicles (AVs). Global Navigation Satelite System (GNSS) provides satellite-based PNT services. However, a spoofer can temper an authentic GNSS signal and could transmit wrong position information to an AV. Therefore, a GNSS must have the capability of real-time detection and feedback-correction of spoofing attacks related to PNT receivers, whereby it will help the end-user (autonomous vehicle in this case) to navigate safely if it falls into any compromises. This paper aims to develop a deep reinforcement learning (RL)-based turn-by-turn spoofing attack detection using low-cost in-vehicle sensor data. We have utilized Honda Driving Dataset to create attack and non-attack datasets, develop a deep RL model, and evaluate the performance of the RL-based attack detection model. We find that the accuracy of the RL model ranges from 99.99% to 100%, and the recall value is 100%. However, the precision ranges from 93.44% to 100%, and the f1 score ranges from 96.61% to 100%. Overall, the analyses reveal that the RL model is effective in turn-by-turn spoofing attack detection.
