| 摘 要： | 为解决基于IEEE 802.11协议的CBTC(Communication Based Train Control,基于通信的列车运行控制)无线数据通信子系统中存在的不安全因素,应引入安全通信协议,采用加密技术进行防护。鉴于降低成本及易实现性等方面的考虑,设计中选用Rijndael加密算法,并用VC++对该算法进行软件编程。最后,借助Socket通信机制模拟数据加解密通信过程,验证了设计的正确性。测试结果表明,该软件算法设计正确,安全性好,易实现,可运用到CBTC安全通信协议中,确保列控信息的安全传输。

| Abstract: | In order to avoid the unsafe factors in CBTC( Communication Based Train Control) wireless data communication subsystem of urban rail transit,safety communication protocol and its encryption technology should be used. In view of the low cost and easy implementation,Rijndael algorithm is chosen,and VC + + is used to complete the software programming. Finally,in order to validate the correctness of the design,socket communication mechanism is employed to simulate the encryptiondecryption data communication process. The test results prove that this algorithm is correctly designed,safe,easy for implementation and applicable in CBTC safety communication protocol to ensure safe transmission of train control information. |
