Abstract: Because of the application of emerging technologies such as software defined vehicles, autonomous driving, intelligent connected vehicles, and vehicle road collaboration V2X, intelligent connected vehicles face severe safety risks and challenges. In order to improve the cyber security level of a new vehicle model, based on the brand-new technical framework platform iDEA, this paper analyzes the vehicle cyber security from the four dimensions of the cyber security target—security, privacy, property loss and non-security function. According to the identified cyber security risk and disposal decision, a reasonable cyber security mechanism is established. Designing controllers's cyber security based on the new vehicle cyber topology, it greatly improves the protection level of cyber security of the model.
