Mitsubishi Electric Develops World’s First Attack Algorithm for Sensors Used in Drones, Cars, Production Equipment and More
Mitsubishi Electric has developed world’s first sensor-security technology that detects measurement-data inconsistencies by embedding a proprietary algorithm in sensor fusion algorithms, which combine multiple sensors for measurements used in the automatic control of drones, in-vehicle devices, production equipment and more. Mitsubishi Electric’s new algorithm detects malicious attacks based on more than 42 percent inconsistencies in measurement data. In the case of ultrasonic attacks on drones, for example, the Earth’s magnetism or gravity is calculated in two ways using intermediate values in the sensor fusion algorithm, and any difference between the two results is treated as an inconsistency.
The new algorithm can be implemented at low cost as additional software in existing sensor signal processing circuits without the need to add or modify hardware. The accuracy of sensor measurements is not compromised. The new sensor security technology can be added to devices such as drones at low cost because it can be implemented in existing sensor-signal processing circuits without having to modify the hardware or make any other addition.
