Research on application technology of online key management system for new train control system of intercity railways
Focusing on the hidden dangers of information transmission in the mobile communication network of the new train control system,which is caused by the participation of many operators and equipment manufacturers in the process of promoting regional integrated transportation services on intercity railways,referring to the technical principles of online key management of the European train control system,combining with the specific requirements of network security and information secrecy of the new train control system of intercity railway,the application scenario analysis is conducted on both the software hardware structure of the system,and the requirements of function transfer ability and the verification process of the simulation test are studied.Then a set of system-level train operation safety control information key management plan with strong technical protection means and high implement ability is offered.This plan aims to meet the actual needs of multi-operator cooperative transportation,and introduces the expected application effect of online key management system on the information security protection capability of the new train control system of intercity railway.
