Abstract: As the communication buses of intelligent networked vehicles become more and more abundant, the risk of safety exposure of the traditional CAN communication bus is getting higher and higher. Currently, there is an urgent need for information security protection for vehicle-mounted networks to improve the privacy, accuracy, and reliability of vehicle-mounted communications. This article mainly introduces the security protection principle of in-vehicle network. By citing encryption and decryption algorithms, fresh value information, identity verification and other related technologies, the in-vehicle network security protection is low-cost, fast and effective in a short period of time, and the intelligent network connection is improved. The level of car information security protection.
