【摘要】 论文通过分层安全模型研究了IEEE802.11WLAN安全性协议的性能以及在多用户、拥塞和非拥塞情况下,不同安全机制对安全网络性能的影响,从而论证了在对无线网络性能影响有限的情况下,WEP与802.1x结合使用,采取集中认证和动态密钥管理机制,可以获得比WEP更好的无线网络安全性。更多还原

【Abstract】 With layered security model,this paper studies the security protocol and performance of IEEE802.11 WLAN,different security mechanisms’ effects on the security performance under condition of multi-client,congested and un-congested networks.Thus it proves in case of having a limited effect on performance of the wireless network,combining WEP and 802.1x,using centralised authentication and dynamic key management,we can obtain the security of wireless network better than WEP.更多还原
