面向时延敏感的TRDP安全防护机制
Security scheme for time-critical TRDP message
摘要
Abstract
As train communication technology advanced,the environment of train control networks became increas-ingly complex,with more network bandwidth being demanded by on-board devices and greater complexity emerg-ing in network topology.Consequently,the physical layer carrier for train internet gradually transitioned from serial communication bus networks to Ethernet.To ensure the normal operation of the Ethernet protocol stack in the train internet and meet the unique requirements of the train internet,the TRDP protocol was proposed by the TCN alli-ance and has now become an essential part of data transmission for on-board devices.However,with the introduc-tion of the Ethernet architecture,traditional computer network security risks were also brought into the train com-munication network.The TRDP protocol,built upon Ethernet,lacked effective security protection mechanisms and faced a series of risks such as malicious attacks,data leakage,and denial of service.Based on the TRDP protocol,the differences and requirements of its two protocol modes,message data and process data,were analyzed.Suitable encryption protocols in line with the actual situation of the train internet were selected,protocol details were im-proved,and a security scheme based on encryption protocols was designed.Furthermore,a model system was con-structed on this foundation.The system demonstrates how these key security technologies can be combined to build a secure TRDP train information system and proves that it can meet the performance requirements of the train inter-net for the TRDP protocol while ensuring the security of the protocol.关键词
