铁路数据通信网安全技术及其发展

Security Technology and Development of Railway Data Communication Network

随着我国铁路数据通信网络的逐渐完善,现在的铁路数据通信网主要由客专数据通信网、铁路运输管理信息系统网和铁通划转数据通信网3个子网络组成,且它们之间的运营和维护相互独立。如今,铁路数据通信网涉及GSM-R系统、综合视频监控、铁路电报系统、视频会议系统和应急通信系统等10多种相关的业务,但是目前我国针对铁路数据通信网的安全技术采取的手段不够完善,所以将从审计和安全管理等方面进行安全研究,并对其发展进行展望。

With the gradual improvement of China's railway data communication network,the current railway data communication network is mainly composed of three sub networks:passenger dedicated data communication network,railway transportation management information system network and railway transit data communication network,and their operation and maintenance are independent of each other.Nowadays,the railway data communication network involves more than 10 related services such as GSM-R system,integrated video monitoring,railway telegraph system,video conference system and emergency communication system.But at present,the security technology of railway data communication network in our country is not perfect enough,so we will do security research from audit and security management,and look forward to its development.
