摘要:

安全关键型信息物理系统(CPS),例如四旋翼无人机,尤其容易遭受网络攻击,若未能及时准确检测,将引发严重后果。在户外作业期间,无人机系统的非线性动力学特性叠加非高斯噪声,对传统统计方法与机器学习方法的有效性构成挑战。为克服这些局限,我们提出QUADFormer——一种基于Transformer架构的先进四旋翼无人机攻击检测框架。该框架包含残差生成器,可生成对异常敏感的序列,再由Transformer分析这些序列以捕捉统计模式,实现检测与分类。此外,其警报机制可确保无人机即便在受攻击时也能安全运行。大量仿真与实验评估表明,QUADFormer在检测精度上优于现有前沿技术。

英文摘要:

Safety-critical cyber-physical systems (CPS), such as quadrotor UAVs, are particularly prone to cyber attacks, which can result in significant consequences if not detected promptly and accurately. During outdoor operations, the nonlinear dynamics of UAV systems, combined with non-Gaussian noise, pose challenges to the effectiveness of conventional statistical and machine learning methods. To overcome these limitations, we present QUADFormer, an advanced attack detection framework for quadrotor UAVs leveraging a transformer-based architecture. This framework features a residue generator that produces sequences sensitive to anomalies, which are then analyzed by the transformer to capture statistical patterns for detection and classification. Furthermore, an alert mechanism ensures UAVs can operate safely even when under attack. Extensive simulations and experimental evaluations highlight that QUADFormer outperforms existing state-of-the-art techniques in detection accuracy.
