无线局域网环境下的安全体系结构研究

Study on Security Architecture of Wireless LAN

无线局域网是当前的研究热点之一,文中针对现有的多种WLAN网络安全访问机制,包括SSID、MAC地址过滤、WEP、802.11i、IPSecVPN、WPA等方案,分别讨论和分析了它们的应用方式以及优缺点。在此基础上,提出了一个新的具有访问力度选择功能的WLAN安全模型-WOS,该模型可为客户端提供可选择的安全访问力度,以及辅助决策的服务功能,讨论了WOS的体系结构,分析了其访问流程。

Wireless local area network is one of the hotspots in today's research work. This paper discusses and analyses the application mode, advantage and disadvantage of kinds of WLAN network security access mechanism including SSID, MAC address filtering, WEP, 802.11i , IPSec VPN, WPA. And we also propose a new WLAN security model-WOS which has ability to choose the accessing power. This model can provide client with optional security accessing power and the ability of assistant decision. We discuss the architecture of WOS and analyses the accessing flow.
