Study on the security architecture for intelligent transportation systems

摘要

ITS (Intelligent Transportation Systems) supports a lot of communication services, such as reservation service, payment service, driver support service and etc, by connecting various kinds of communication systems. However, no security architecture to cover wider area of such ITS communication services has been proposed. Therefore, this paper proposes security architecture for ITS services. Precisely speaking, we analyze the risk against four typical ITS services, and summarize security functionality for these ITS services to derive security architecture. Finally, we propose a few concrete security mechanisms for some specific ITS services in order to show the feasibility of the proposed security architecture.
