摘要
摘现有的GSM—R身份认证协议是单向认证，会给正常的铁路生产带来安全隐患。针对这一问题，提出一种应用AES算法在GSM—R中进行身份认证和密钥协商的方案。该方案仅使用AES算法可实现双向认证且易于实现，拥有和当前使用的GSM—R相似的认证流程。此外，该方案具有保密性高、计算复杂度低、传输参数少的优点，大大提高了铁路日常工作的灵活性和安全性。
Existing GSM-R identification authentication protocol is one way and will give the normal railway production safety hazard.In this paper we present a new Identity Authentication Protocol in GSM-R Network Environment with AES algorithm in the identification authentication and key negotiation.This protocol is easy to carry out and used for two-way authentication.The process of Identity Authentication is just similar to the process of GSM-R.The advantages of this protocol are higher security, low computational complexity and fewer parameters of transmission, which increase the daily work of the flexibility and security.
