一种列车数据安全处理架构及实现

Train Data Security Processing Architecture and Implementation

工业以太网的大带宽、高实时性、高可靠性等优点使其成为下一代列车网络系统的发展方向,如何加强基于以太网的列车网络安全成为一个亟待解决的问题。提出一种列车数据安全处理架构及实现方法,在满足列车通信需求的前提下,解决了列车网络与地面服务平台间的信息传输安全、维护终端接入列车网络访问控制等问题,降低了列车网络遭受攻击的风险,提高了列车网络的稳定性,确保列车的安全运营。

The advantages of industrial Ethernet such as large bandwidth,high real-time performance,and high reliability make it the development direction of the next-generation train network system.How to strengthen the security of the train network based on Ethernet has become an urgent problem to be solved.This paper proposes a train data security processing architecture and implementation method.Under the premise of meeting the train communication requirements,it solves the problems of information transmission security between the train network and the ground service platform,and access control of maintenance terminals connected to the train network.It reduces the risk of train network being attacked,improves the stability of the train network,and ensures the safe operation of trains.
