| Abstract | In the last years, the automotive industry has experienced a technological revolution driven by the increasing demand of connectivity and data to develop driver-assistance systems, autonomous vehicles, and improve the mobility experience. To provide higher bandwidth in in-vehicle communication networks (IVNs), carmakers are choosing Ethernet technology, which becomes Automotive Ethernet when applied in IVNs. However, with the rise of vehicle connectivity, the cybersecurity of vehicle systems has become a primary concern for the automotive industry. To address this issue, we conducted a systematic review, deeply analyzing the impact of Automotive Ethernet on security, safety, and comparing it with the current in-vehicle communication solutions like CAN protocol. We retrieved the key security attacks and mitigations proposed in the current literature to highlight their significance, including a mapping between the regulation UNECE WP.29 R155 and the retrieved answers. We found that the industry has only implemented some automotive-dedicated Ethernet solutions to date. In the near future, the vehicle and road ecosystems may require more exclusive automotive solutions to meet specific constraints such as low latency. Our results can provide a comprehensive baseline, both for industry and academia, for the current and future development of Automotive Ethernet. |
