Intentional Electromagnetic Interference Attack against Infrared Thermal Imaging Sensor

Abstract

Infrared thermal imaging camera can be used to measure the temperature of the target object or detect the existence of the object by generating the thermal image of the object, thus it is widely used in the military and civil fields, and plays a key role in human daily life. As the core module of the infrared thermal imaging camera, the infrared thermal imaging sensor is an indispensable part of the infrared thermal imaging camera. Infrared thermal imaging cameras rely on infrared thermal imaging sensors to measure temperature and perform thermal imaging. If the infrared thermal imaging sensor detects the temperature wrong, there will be serious consequences of delaying the military situation in the military, and will seriously affect the production and life of the society in the civilian field. In this work, it is demonstrated that intentional electromagnetic interference can affect the communication process of the infrared thermal imaging sensor MLX90640. The data transmission line between MLX90640 and MCU can be tampered with through intentional electromagnetic interference attacks, which eventually lead to temperature numerical errors and abnormal infrared thermal image display.
