Abstract
As a core component of future transportation systems, intelligent connected vehicles have seen their information security issues become a critical factor constraining industry development. With the rapid advancement of vehicular networking technologies, the information security threats faced by vehicles are becoming increasingly complex and diversified, necessitating the establishment of a comprehensive security protection system to ensure driving safety and user privacy. This study focuses on exploring key technologies for the information security of intelligent connected vehicles and proposes an integrated solution based on a multi-layered defense mechanism. By analyzing mainstream attack methods and their potential risks in conjunction with real-world application scenarios, a novel security architecture incorporating identity authentication, data encryption, and intrusion detection is designed. Innovatively, this architecture integrates blockchain technology and edge computing approaches, substantially enhancing the system's resilience to attacks and real-time response efficiency. Experimental results demonstrate that the proposed solution exhibits significant advantages in safeguarding communication security, preventing unauthorized access, and reducing latency, effectively addressing security challenges under various complex scenarios. The primary contribution of this research lies in proposing a security fr amework that combines flexibility and robustness, providing theoretical support and technical references for the information security assurance of intelligent connected vehicles while laying a solid foundation for subsequent related studies.
