Abstract
An attack detection method includes determining a sampling rule including a sampling interval and a sampling time on the basis of at least one of a statistic indicating a variation in sensor values included in the sensor data or event information on the mobility entity, which indicates the timing of a change in sensor values; generating sampling data including two or more sensor values selected from the sensor data on the basis of the sampling interval and the sampling time, first order information, and second order information; and calculating a first anomaly score indicating the degree of anomalies in the evaluation target data and a second anomaly score indicating the degree of anomalies in the evaluation target data, determining on the basis of the calculated first and second anomaly scores whether the evaluation target data has resulted from the attack, and outputting a determination result.
