Abstract: More and more wayside equipment and systems based on the Chinese train control system are developed, which formed the complex information interaction between the connected equipment and caused the increasing security vulnerabilities in the system itself. It will seriously threaten the safety of railway transportation once these vulnerabilities are exposed to attackers. So, it is particularly important to protect against information security of train control system. Taking the Chinese train control system as the research object, this paper preliminary analyses the current information security risks hiding in the system, and generally describes the technical thinking of information security protection needed by the development of Chinese train control system, which can provide a forward-looking and exploratory basis for the equipment design and technical development of the next generation of Chinese train control system.

Key words: train control system, information interaction, information security, vulnerability, technical development
