A Review of Intrusion Detection Methods for In-Vehicle Networks at the Semiconductor Level
Keywords:
In-Vehicle Networks, Intrusion Detection Systems, Automotive Cybersecurity, CAN Bus, Semiconductor Security, Hardware-Based IDSAbstract
The rapid digitalization of modern vehicles has significantly increased their exposure to cyber threats, particularly within in-vehicle networks (IVNs) such as the Controller Area Network (CAN). While numerous intrusion detection systems (IDSs) have been proposed at the software level, recent research highlights the growing importance of semiconductor-level intrusion detection to meet stringent real-time, safety, and reliability requirements. This paper presents a comprehensive review of intrusion detection methods for IVNs with a specific focus on hardware-assisted and semiconductor-integrated approaches. A structured literature review of recent studies is provided, followed by a comparative analysis of detection techniques, architectural implementations, and performance characteristics. The paper also discusses key challenges and future research directions toward secure, low-latency automotive semiconductor platforms.
