Security Assessment of Temporary Speed Restriction Server
摘要
Abstract
In recent years, with China’s rapid development of high speed railways, more and more high speed railway lines have been put into operation effectively, alleviating the pressure on China’s railway travel. But fre-quent railway accidents have caused great threat to people’s life and property security. It is urgent to probe into how to ensure the safe operation of the railway. Temporary speed restriction server is an important part of CTCS-3 train control system whose safety directly affects the safe operation of high-speed railway. Combined with the actual operation of the temporary speed restriction server process, by use of the security analysis software –SIMFIA to build simulation model of temporary speed restriction server, this study automatically generated the fault tree of the system, and calculated the minimal cut sets of the failed state. According to the fact that mini-mum cut sets can quickly find fault source, it analyzed the security of temporary speed restriction server.关键词
