摘要
现有的GSM-R身份认证协议,是对SIM卡的身份认证而不是对铁路员工的身份认证,在日常铁路生产中,移动台容易丢失也容易被盗窃,使得SIM卡信息有可能泄露,导致SIM卡被克隆,给正常的铁路生产带来安全隐患.针对这一问题,本文设计了一种新的身份认证协议,通过在移动台使用用户口令作为认证密钥,不仅实现了对人的认证,而且实现了认证实体之间的双向认证,使得铁路员工可以使用任意的移动台进行通信,提高了日常工作的灵活性和安全性.
Currently, the identification protocols for GSM-R networks have been designed for SIM identification rather than user identification. In the day-to-day rail production, the mobile station may be stolen and lost easily,so the SIM information may be leaked, which may lead to cloning of SIM, and bring threat to normal rail production. To solve this problem, we design a new identification protocol in which the mobile station takes the user＇s password as the identification key. It can not only identify the user, but realize the two-way identification between entities as well. The proposed identification protocol can make the railway staff use any of the mobile station to communicate, and improve the flexibility and security of the day-today rail production.
