Research on the System of Hardware Security Protection Module of Automobile Chips Based on HSM Vehicle Network

This paper proposes a system of hardware security protection module of automobile chips based on HSM (hardware security module) vehicle network, aiming to improve the hardware security of automobile chips. First of all, the system architecture includes an HSM-based vehicle network security protection module, which can effectively resist the risk of external attacks. By integrating the hardware security module in the automobile chip, it is ensured that the chip has strong data encryption and identity authentication capabilities when facing malicious attacks. This paper proposes a security protocol based on key management and encryption algorithm, which can perform efficient information transmission in the vehicle network and ensure the data integrity and confidentiality during the communication process. In order to verify the effectiveness of the design, this paper conducts system simulation and accurately evaluates the performance of the protection system through data analysis. The simulation results show that the proposed security protection module can significantly improve the security of the system and prevent the success rate of external attacks from less than 5%. At the same time, the system also shows good performance in terms of processing speed and resource consumption, which is suitable for application in actual vehicle networks.
