摘要
从CBTC信号系统无线网络的安全需要出发,介绍了CBTC信号系统无线网络的系统结构,通过研究无线网络结构中关键安全部件(SD)所采用的安全算法和密钥的安全性,理论分析计算出CBTC信号系统DCS无线网路系统的安全性。
Based on the needs of CBTC signaling system wireless network security, this article describes the system structure of CBTC signal wireless network. Through studying the encryption algorithms and the security of the encryption key used in the confidentiality security devices of the wireless network, the se- curity of the DCS wireless network for CBTC signaling system is calculated by theoretical analysis.
