Intelligent Networked Vehicle CAN Network Security

With the continuous development of Internet technology, the emergence of Internet cars, network technology and automotive processes are becoming more and more closely linked, automotive network security has become an important part of automotive security, the wrongdoers are able to control the car’s power system and maneuvering system, no matter what kind of attack the ultimate goal is to take advantage of the lack of security mechanisms of the vehicle CAN bus network, by obtaining the vehicle CAN bus access, send messages to the CAN bus, and directly control the vehicle to protect the CAN bus from attacks, so ensuring the security of the automotive electronic system is one of the important issues in the design of the automotive electronic system, this paper designs a clock drift intrusion detection method, this system evaluates the performance of the system when using different classification algorithms, and by introducing a dynamic threshold detection algorithm, the false alarm rate can be reduced.
