In order to scientifically and systematically evaluate the security risk of the Internet of vehicles and build a strong security guarantee system of the Internet of vehicles, based on the situation awareness technology, a method of assessment for the security risk of the Internet of vehicles is puts forward innovatively. An Internet of vehicles security risk assessment index system including 3 levels and 18 indicators is constructed through the acquisition of situation elements. Through the exponential scale analytic hierarchy process, the security risk assessment model of the Internet of vehicles is established to understand and analyze the security situation of the Internet of vehicles. Finally, an example is given to prove the effectiveness of the proposed assessment method. The results show that the application of situational awareness technology to assess the security risk of the Internet of vehicles in a rapidly changing environment can globally and dynamically describe the current state of the Internet of vehicles and assess the risk.The analytic hierarchy process based on exponential scale is used to build the security risk assessment model of the Internet of vehicles, which can more truly and effectively reflect the risk situation of the current state of the Internet of vehicles. The example calculation results show that the safety risk assessment method proposed in this paper is accurate and effective, and has a wide range of applications.
