The paper also points out the difficulty of defending systems against these attacks: adding technology to authenticate the perceived dots, for example, could slow things down too much in an autonomous vehicle. Researchers at the Korea Advanced Institute of Science and Technology have exposed two weaknesses in the LIDAR (light detection and ranging) sensors used in autonomous vehicles. The researchers found that a single pixel on one sensor can be fooled by multiple pixels from another sensor. LIDAR sensor with a saturation attack by capturing the sensor's emitted laser pulse and sending it back. The second test used refraction to change the apparent direction and distance of a point cloud, the sensors' way of detecting objects. "Fake [points] in directions other than the direction of the attacker can be a severe threat to the victim," the team wrote.
