Problems solved by technology

[0004] However, since there is currently no network security protection solution suitable for vehicles, vehicles will inevitably face network security problems after they are connected to the network, such as leakage of vehicle owner information, leakage of communication information, tampering of vehicle software, tampering of vehicle control data, and malicious software. Any intrusion will bring great risks to the driving safety of the vehicle and the safety of the owner.
[0005] It can be seen that there is a large network security problem in the vehicle networking in the prior art
