Title:
攻撃検知装置、攻撃検知プログラム及び攻撃検知方法
Document Type and Number:
Japanese Patent JP6746037
Kind Code:
B2
Abstract:
A correlation calculation unit (21) receives magnetic data and acceleration data, which are sensor data, from a sensor fusion unit (12a), and calculates a correlation value. An attack determination unit (22) acquires the correlation value from the correlation calculation unit (21), and acquires, as error data, a gravity vector error and a geomagnetic vector error that are calculated in the process of sensor fusion from the sensor fusion unit (12). The attack determination unit (22) determines the presence or absence of an attack on an inclination sensor module (1a) by comparing the correlation value with a threshold value corresponding to the correlation value and comparing the error data with a threshold value corresponding to the error data.
