Although self-driving car time has not yet come, but it has been long begin to pay close attention to its security. American security innovation, chief scientist Jonathan Petit published a paper introduces in detail how to crack the laser radar sensors on the driverless cars.

Pettit says he USES a weak laser and pinger device can "cheat" driverless cars "see" the object of does not exist.

Laser radar is a kind of similar to radar system, it USES a pulse laser to create a 3 d image in the world. In some driverless cars, laser radar ACTS as a car's eyes. However, laser radar map 3 d images can be forged.

Pettit said that hackers can forge some actual does not exist around the driverless cars obstacles, unmanned systems by laser radar to detect these "obstacles", will stop or escape, as a drunken man, driverless cars will be difficult.

Petit, said he had within 20-350 meters from the laser radar virtual created that doesn't exist obstacles, such as car, walls, etc., not only that, he will also be able to make the unmanned vehicle tracking system paralyzed, unable to identify the real obstacles.

Although the hole is currently only exists in Ibeo Lux laser radar, but pettit said, this is not because Ibeo Lux performance is poor. Manufacture of laser radar equipment company, he thought, there is no aware of the risk of such attacks.

Pettit said, while he was in when former researcher at university college cork in Ireland has been the study. After all, he says, people need not panic, which risk exists only in the unmanned vehicle technology. Petit research also gave us a wake, driverless cars to really popular, there are still many challenges to face.
