Abstract: | Intelligent connected vehicles have promoted the innovation and development of transportation;however, ICVs are challenged by network security issues. The intrusion detection technology, as a lightweight defense technology, includes effective detection based on the established features of attacks, further analysis and defense of the attack. This paper investigates the intrusion detection technologies to prevent common in-vehicle network attacks in recent years, classifies these technologies based on shared characteristics and methods, and compares the advantages and limitations of different technologies. The paper provides a reference for the research and development of in-vehicle network intrusion detection. |
