Hackers or "global users" in a broader sense are not always trying to seize control. You may only want to implant some information, or insert some code, and you can't rule out pure pranks without purpose. But in terms of the target, there are nothing more than two: the end attack (attacking the vehicle itself) and the pan-net attack. The latter includes all external nodes of the network, intelligent transportation, and cloud servers. Given that the latter has not yet been established, the guess of the attack mode can only be referenced to the existing network.

There have been hackers trying to flood the data channel by sending garbage packets, which is a disguised blocking attack. Although the data of the cloud platform itself is secure, communication between the terminal (vehicle) and the cloud platform will be blocked. The hacker still has the opportunity to pretend that the cloud sends a "studded" data packet to the terminal, and the terminal may have defects in the verification capability of the remote frame and the data frame, and the terminal control right is temporarily hijacked. There is still a systemic hazard for the entire cloud command system.

We assume that the cloud of the road (or the entire city) has accumulated enough traffic big data to digitize the entire city. Every centimeter of road is digitized, and the transportation facilities also have intelligent features that generate data streams. Cars, not human drivers, can sense traffic signals and road conditions, and each car can “talk” to the road. The road will tell how it will travel, how far it will encounter obstacles, and suggest the best treatment strategy.

These data chains are updated in real time in sub-milliseconds, and local intelligent decision algorithms will be simple, and you will never have to exhaust all possible conditions. The danger is that all traffic participants rely heavily on the network.

As described in "Speed ​​and Passion 8", hackers use the "Eye of the Eyes" system to "bulk" thousands of cars. And no matter how technically implemented, the cloud command mechanism itself provides the possibility to mass-produce "zombies".

In the era of manned driving, traffic accidents in the city are usually small and affect only local areas. But the blackout of the entire network, the huge security incidents, the prospects of the entire city are terrible, and we are absolutely unable to withstand the global control of the traffic network.

Technology has always been a double-edged sword. We have not denied the invention of the car because we lost 1.2 million people in the car accident every year on the planet. The Internet of Vehicles has not yet been established, and security issues have been put on the agenda. Without exception, vehicle manufacturers promote the physical security of their products, and data security must be added in the future. They believe they can deal with hacker attacks (even if they are just mock attacks), while technology companies believe that car network security can jeopardize the car network itself. They can't all be correct, but the cost of trial and error is too high, leaving us with less time to choose.
