Although the era of driverless cars has not yet arrived, people have begun to pay attention to its safety very early. A paper published by Jonathan PeTIt, chief scientist of US security innovation, details how to crack lidar sensors on driverless cars.
Petit said he uses a weak laser and pulse transmitter device to "cheat" the driverless car to "see" an object that does not exist.
A laser radar is a radar-like system that uses a pulsed laser to create a 3D world picture. In some driverless cars, the laser radar acts as the eyes of the car. However, 3D images drawn by lidar can be forged.
Petit said that hackers can forge some obstacles that are not actually present around the driverless car. After the driverless system detects these "obstacles" through the lidar, it will stop or evade, just like a drunk. People, such a driverless car will be difficult to move.
Petit said that he has virtually created obstacles that are not in the range of 20-350 meters from the laser radar, such as cars, walls, etc., and he can also make the driverless car tracking system paralyzed. Unable to identify real obstacles.
Although this vulnerability currently only exists on the Ibeo Lux laser radar, Petit said that this is not because of the poor performance of Ibeo Lux. He believes that companies that manufacture laser radar equipment are not aware of the risk of such attacks.
Petit said that he had already started the research when he was a researcher at the National University of Ireland. He said that people do not need to panic, after all, the risk of this attack only exists in driverless car technology. Petit's research also gave us a wake-up call, and the driverless car wants to be truly popular, and there are still many challenges to face.
