Cyber Security Risk Analysis and Evaluation for Intelligent Vehicle Gateway

With the rapid development of intelligent vehicle industry, the application of network technology and communication technology has gradually spread to all levels of vehicles. While bringing innovative functions and experience, it also infuses a new security risk - cyber security risk. This paper analyzes and evaluates the cyber security threat and risk for vehicle gateway which is a key component of automotive, and puts forward a method of risk grading, analyzes the security state of gateway, and evaluates the security risk level of gateway based on the common characteristics. Using this method, the integrity and rationality of risk analysis of intelligent networked vehicles can be effectively improved. Combined with quantitative data analysis, the risk status can be expressed and the risk level of the analysis object can be effectively displayed.
