With the rapid development of modern cities, urban rail transit is becoming an important means to alleviate urban traffic congestion and achieve green travel with its advantages of safety, punctuality, efficiency and environmental protection. At present, Communication-based Train Control System (CBTC) is the most widely used operation control system in the urban rail transit system. The train-ground communication system is a crucial part of the CBTC systems. Handover in train ground communication system happens frequently, which make it vulnerable to jamming attacks. In this paper, the stochastic game is used to model the handover process in the CBTC system when jamming attacks are launched against it. With the objective to minimize the train control energy consumption and train operation curve tracking error, the optimal defense strategy of the system is calculated. Extensive simulation results illustrate the effectiveness of our optimal strategy.
