GSM网络环境认证协议的研究

Identity Authentication Protocol in GSM Network Environment

针对现有的对GSM的攻击,提出一种应用AES算法在GSM中进行身份认证和密钥协商的方案。该方案易于实现,仅使用AES算法,不需要对GSM现有的数据库进行变动,认证流程也与正在使用的GSM认证流程相似。此外,该方案还有保密性高,计算复杂度低,传输参数少的优点。文章最后给出了协议的安全性分析和实现效率的分析。

In this paper we present a new Identity Authentication Protocol in GSM Network Environment with arithmetic AES to prevent the attacks on GSM network. This protocol is easy to carry out.It uses arithmetic AES only and need not change the database of GSM at all. The process of Identity Authentication is just similar to the process of GSM. The advantages of this protocol are higher security, low computational complexity and fewer parameters of transmission. The security and the efficiency analysis are given at the end of this paper.
