Security of self-driving car from the point of view of in-vehicle system

As the technology of self-driving cars are being developed, security and safety are becoming important issues. The communication channel of the self-driving car is divided into external network and internal network. The external network is used for inter-vehicle communication or vehicle-to-infrastructure communication. On the other hand, the internal network, which is called the In-Vehicle network, is used to control the functions of the vehicle. Although the In-Vehicle network is a critical part of the vehicle, it is exposed to many threats. In this paper, we examined the primary functions of self-driving cars and reviewed the recent studies on the security of self-driving cars. Furthermore, we derived various attack scenarios from the In-Vehicle system perspective and analyzed the security requirements.
