摘　　要：针对轨道交通领域网络设备中常见的的总线通信数据传输故障问题,该文研究了安全通信标准和模型,参考EN50159中的安全通信防护技术,设计了一种适用于总线型网络的安全通信协议。通过在应用层和通信底层中加入安全协议层,以应对通信传输过程中的干扰和威胁。搭建试验设备,模拟向总线传输系统注入不同种类的故障,结果表明安全通信能够应对识别数据报文错误,提高了数据安全性和系统可靠性。Aiming at the common problem of bus communication data transmission failure in the field of rail transit network equipment,this paper studies the standard and model of secure communication,and designs a secure communication protocol for bus network with reference to the secure communication protection technology in EN50159. The security protocol layer is added to the application layer and the communication layer to deal with the interference and threat in the communication transmission process. The test equipment is set up to simulate different kinds of faults injected into the bus transmission system. The results show that secure communication can deal with the identification of data message errors and improve data security and system reliability.
