摘要
分析GSM-R移动通信系统中安全保密体系的特点和存在的安全隐患。针对单向认证无法避免假基站攻击的缺陷, 讨论GSM-R 中使用双向认证的思路。探讨基于端到端加密技术在GSM-R中构建安全虚拟专网的实现方法。
In this paper, the characteristics and potential threats of the security architecture of GSM-R system are analyzed. To cope with the intrusion of fake base station in uni-directional authentication, a bi-directional authentication protocol for GSM-R system is discussed. Finally, implementation issues of secure GSM-R VPN based on end-end encryption is studied.
