Abstract: Recently, research on autonomous driving technology has been actively carried out. However, the research on security technologies for various services provided by autonomous navigation technology and collaborative intelligent vehicle traffic system is also active. However, the debate on security technology is still unclear. The reason for this is that implementation accuracy and standards for autonomous navigation technology and collaborative intelligent transportation system technology are not yet clear. However, it is still necessary to look at aspects of security services including reviews of attacks and risks. For this purpose, this study has begun. The focus of this study is understanding of services and understanding of security service technologies in autonomous navigation technology and collaborative intelligent transportation system technology. Therefore, this study focuses on the policy issue and direction of the EU security service, the issue of privacy information and the security and safety issues considered in the platform. We also analyzed the performance of existing researches in relation to safety and safety of related vehicles. In this study, we find out the security issues required by the collaborative intelligent transportation system platform, focusing on EU. It is necessary to establish an appropriate regulatory framework based on PKI to establish a common and standardized C-ITS trust model or certificate policy across the EU and to establish compliance assessment and governance. This research is useful in understanding the importance of security and safety when studying collaborative intelligent transportation systems or autonomous navigation technology and the security requirements and current situations discussed. It also suggests that ultimate discussion is needed on how to proceed with the evaluation of personal information impacts in case of CAM or DENM messages.
