摘要:
城市轨道交通作为城市的关键基础设施,其网络安全问题尤为重要。尽管传统的防护安全机制已经应用到城市轨道交通系统的各个子系统中,但仍应进一步监视CBTC(基于通信的列车控制)系统更底层的进程级活动。提出了一种针对CBTC系统底层信号的新型入侵检测技术,分析了其与传统入侵检测方法之间的区别,阐述了该新型技术的工作原理和工作过程。通过对某条城市轨道交通线路CBTC系统采集得到的真实数据进行仿真试验,验证了该新型入侵检测技术的有效性。
Abstracts:
Urban rail transit is the key infrastructure of city, the network security of which is particularly important. Although the conventional protection safety mechanism has been applied to each subsystem of the urban rail transit system, the lower-level processlevel activities of CBTC should be further monitored. A new intrusion detection technology for the underlying signal of CBTC system is proposed, and the difference between this and the conventional intrusion detection method is analyzed. The working principle and process of the new technology are expounded. The effectiveness of the new intrusion detection technology is verified by simulation experiments on the real data collected by the CBTC system of an urban rail transit line.
