Abstract: Intelligent vehicles commonly utilize remote diagnostic technology to obtain information about the vehicle's operational status and efficiently resolve vehicle malfunctions. To prevent hackers from exploiting security vulnerabilities in the remote diagnostic system for unauthorized operations that threaten the safety of users' lives and property, this paper conducts information security design and research based on a general remote diagnostic system architecture. Through detailed security threat and risk analysis, this study thoroughly investigates information security protection schemes and key technologies (such as identity authentication, secure storage, etc.), and adopts effective implementation plans. By reverification of threat analysis and risk assessment, it can significantly enhance the protective capabilities of the remote diagnostic system and reduce information security risks.
