Abstract

In order to evaluate information safety level of the train operation control system of urban rail transit, some suggestions on risk management were put forward, information safety risk assessment method for train operation control system was studied. Firstly, equipment composition and train control principle of train operation control system based on communication were introduced. Then, complex network model of train control system was constructed, and the mobile authorization transmission path was proposed to analyze the impact of network attack on train control. Secondly, the attack tree method was used to determine the possibility of network attack events. Finally, method of information safety risk assessment of train operation control system was given, and the simulation was carried out by the semi-physical simulation platform.The research shows that this method can find the weak links in the system and reflect information safety state of system. © 2019 China Safety Science Journal
