Abstract：With the increasing demand for data sharing and large-capacity data communication in rail transit vehicular network system, the high-speed interconnection of various subsystems and the gradual opening of the network, together with the emergence of new viruses (such as “seismic network virus”) and new attacks (such as APT attacks) against industrial control systems in recent years, so vehicular networks are facing increasing challenges of the network information security. This paper mainly studies and designs the information security protection system of rail transit vehicle network, introduces the basic design idea and key technology of this system, and combines the characteristics of rail transit vehicle network, constructs a comprehensive security protection system of deep vehicle network from five directions: subarea, external isolation, internal certification, internal and external auditing, supervision and perception. To provide safety services for train development in the future.
