Many operations in power grids, such as fault detection and event location estimation, depend on precise timing information. In this paper, a novel time stamp attack (TSA) is proposed to attack the timing information in smart grid. Since many applications in smart grid utilize synchronous measurements and most of the measurement devices are equipped with global positioning system (GPS) for prec...

To ensure that unmanned aerial vehicle (UAV) positioning is not affected by GPS spoofing signals, we propose PerDet, a perception-data-based UAV detection approach utilizing machine learning algorithms. Based on the principle of position estimation process and attitude process, choose data gathered accelerometer, gyroscope, magnetometer, barometer as features. Although these sensors have differ...
