Title:
SENSING SYSTEM AND SENSING METHOD
Document Type and Number:
WIPO Patent Application WO/2019/208524
Kind Code:
A1
Abstract:
A sensing system (1) comprising a sensor (2) and a controller (3). In the sensor (2), an acquisition unit (2a) acquires sensor data, a calculation unit (2b) calculates, using the sensor data, a MAC value enabling verification of the sensor data not being falsified, and a transmission unit (2d) transmits the sensor data or, when the calculation unit (2b) has calculated the MAC value, the MAC value instead of the sensor data to the controller (3). In the controller (3), a reception unit (3a) receives the sensor data or the MAC value transmitted from the sensor (2), and, if the reception unit (3a) has received the MAC value, a verification unit (3b) verifies the MAC value using the sensor data that the reception unit (3a) has received just previously.
