认证作为安全应用系统的第一道防线,是重要的安全服务。典型的认证协议是挑战/应答机制。这种认证协议由于结构简单易于实现得到了广泛的应用,但是这种机制对于GSM网络来说,存在用户个人身份信息容易泄露、、外地代理和家乡代理之间没有安全防护机制,容易被恶意分子攻击窃取信息等缺点。本文提出了一个适用于GSM网络的基于简单数学运算和模平方剩余的认证协议。并对协议进行了安全和性能分析,结果表明该协议更强健,安全性更高。
Certification as the first line of defense for security applications is an important security service. A typical authentication protocol is a challenge / response mechanism. This authentication protocol is widely used due to its simple structure and easy implementation. However, this mechanism is prone to leakage of personal identification information of the GSM network. Therefore, there is no security mechanism between the foreign agent and the home agent and is easily attacked by malicious elements Attacks steal information and other shortcomings. This paper presents a simple authentication algorithm based on simple math and modular squared residuals for GSM networks. The protocol was also analyzed for security and performance. The results show that the protocol is more robust and secure.
