列车车载以太网通信系统内生安全策略研究

Research on Intrinsic Security Policy of Ethernet Communication System on Train

轨道交通领域经过多年的发展,以太网逐渐成为列车车载网络的主流技术。以太网技术由于其本身的开放性,安全性始终是用户非常关心的问题,当前阶段的解决方案以边界安全防护为主而往往忽视了车载网络内部的安全性。全球范围内新生时间敏感网络(Time Sensitive Network,TSN)以太网技术正在蓬勃发展,未来该技术很可能成为列车车载网络新的主流技术。提前开展内生安全技术研究,解决当前阶段未能解决的内部安全问题,提升列车整体的安全性。

After years of development in the field of rail transit,Ethernet has gradually become the mainstream technology of train-on-board network.Due to the openness of Ethernet technology itself,security is always the concern of users.The current solutions mainly focus on boundary security and often ignore the internal security of vehicle network.The new Time Sensitive Network(TSN)Ethernet technology is developing rapidly in the world,and it is likely to become the new mainstream technology of train-on-board network in the future.Carry out the endogenous safety technology research in advance,solve the internal safety problems that cannot be solved at the current stage,and improve the overall safety of the train.
