o A Case Study of Vehicular-PKI Establishment for V2X communication of Cooperative-ITS in Korea
V2X (Vehicle to Everything) is the next generation vehicle technology that is being researched and developed not only from the well known vehicle manufacturer (OEM), it is also researched and developed at national level in the United States and Europe. However, as vehicles are converged with IT technology, security threats that existed in preexisting IT environment are also being transferred to vehicles. there has been hacking cases announced around famous conferences which was performed on actual vehicles. If there is a hacking damage case targeting the future V2X environment, security measures are required because it could lead to accidents related to humans. The research on security of vehicle PKI system in the V2X environment has already been carried out much abroad based on IEEE WAVE 1609.2 standard, and in Korea, establishing and demonstrating vehicle PKI system in national industrial aspect based on IEEE WAVE 1690.2 standard is being prepared. This presentation introduces how to build and operate a vehicle PKI system for communication security on ongoing V2X environment in Korea. By comparing with the structure and operation method of public authentication service currently used in Korea, an efficient method for building and operating a real vehicle authentication system will be discussed. Also, a roadmap for building Korea's V2X environment security infrastructure for Cooperative-ITS (C-ITS) will be introduced in the presentation.
