Application Of Security Network Technology In High-Speed Railway Integrated Dispatching System

The railage operation is being built upon the modern computer science and computer network system, along with the fast development of computer science and network technology. The network security is especially important on account of the railage' s status.Building high-speed railway is necessary for the development of our country' s railway. The integrated dispatching system is the most important part and the hardcore of the high-speed railway. The information of traffic, signals, production power and so on, are transmitted in it. This system should have security-network to protect information considering the more and more unsafe factors, which safeguard the traffic security and improve efficiency and service.Firstly, the development of network security and the structure of railway and integrated dispatching system are introduced. Secondly, the author analyzes briefly the methods of cryptographic technology and the component of PKI correlative with this design. In the design of software, the process of building PKI, Key Escrow are explained in detail, and several secure methods of setting for Windows2000 are designed. Finally, the author presents the conclusion and the expansibility of this design.This design has great influence of enhancing the information security of high-speed integrated dispatching system, which ensures railway transportation in the working order.
