无线局域网中的信息安全保护和安全漫游

Information Security Protection and Secure Roam in WLAN

在描述无线局域网中现有安全机制的基础上,提出了一个比较全面的信息安全保护和安全漫游解决方案。采用RADIUS和ESSID认证、MAC地址过滤、WEP加密并动态生成WEP密钥(128位加密密钥)等机制,来保护用户数据的私密性;采用基于MobileIP和RADIUS协议的漫游机制来支持用户在多个接入点之间的漫游,保证用户在进行安全漫游时不中断业务。

In this paper,a new method of information security protection and secure roam is proposed based on the existing security mechanism in WLAN.In order to protect the information privacy of users,some mechanisms such as RADIUS Authentication,ESSID Authentication,MAC Address filtering and WEP,etc.,are used.The protocols of Mobile IP and RADIUS are used to provide continuous service without interruption for users when they move from one AP to another AP.
