摘要:
城市轨道交通信号系统的车地无线通信，其传输的物理介质存在于开放的空间范围内，具有一定的非授权接入风险，需符合EN 50159\|2—2001中所规定的要求。目前车地无线的通信层普遍采用的加密算法，属于国际标准加密算法；而在车地无线通信中传输的应用信息都是与列车运行控制相关的信息，目前尚未应用密码技术。国产加密技术符合我国在重点行业中采用国产密码算法的趋势，有利于保护轨道交通数据安全，尤其在无人驾驶轨道交通系统中，可实现车地无线通信的高安全性和高可靠性。
Abstracts:
The train\|to\|track wireless communication of urban rail transit signal system faces with unauthorized access risks, because the physical medium of signal transmission exists in the open space, that is required by the specified clauses in EN 50159\|2—2001. At present, the encryption algorithm commonly used on the train\|to\|track wireless communication level belongs to the international standard encryption algorithm, and the application messages transmitted are all the information related to train running control, but no cryptography technology has been adopted yet. The Chinese encryption technology discussed in this paper is in line with the trend of encryption algorithm application in key Chinese industries, which is conducive to rail transit data security protection, especially applicable to the driverless system with high security and high reliability in train\|to\|track wireless communication.
