| Abstract: | Communication based train control （CBTC） technology has been widely used in China＇s urban rail transit system. In this paper, the composition and characteristics of CBTC system are briefly introduced. Then the existing information security risks and possibility of being attacked from hackers in train-ground wireless communication subsystem based on IEEE 802.11 protocol are described. The existing problems of current information security measures in wireless CBTC system are analyzed. Finally, the focus of our research in the future in order to strengthen the security and reliable operation of rail transit is proposed. |
