Abstract: With the continuous improvement of automobile intelligence, networking and electrification, driven by the new 5G infrastructure policy, the Internet of vehicles is expected to usher in great development，but the information security problems faced by the Internet of vehicles are becoming more and more prominent. This paper firstly analyzes the trend of the Internet of vehicles, as well as various security risks faced by it, and proposes that the security not only needs to establish a defense system in depth from the cloud, the pipe, the vehicle and the mobile end, but also should shift the focus of security to the vehicle end, and the v2x HSM (hardware security module) is the core and cornerstone to effectively ensure the security of the vehicle end..
