| 摘 要： | 现有的无线局域网(WLAN)基础设施都是支持IEEE802.11犤1犦或802.11b犤2犦标准的,但这些标准中所定义的加密和认证协议———WEP(WiredEquivalentPrivacy)协议存在着很多的安全漏洞,因此,论文在总结了WEP协议的各种安全漏洞之后,提出了两种弥补漏洞、提高WLAN安全性的方案:一种是在对现有WLAN基础设施改动很小的条件下,提出的临时改进方案,另一种是为了架设新的WLAN基础设施而提出的安全方案。

| Abstract: | Currently,the infrastructure of most WLANs supports IEEE802.11 1 standard or802.11b 2 standard.However,there are many securtiy flaws in the Wired Equivalent Privacy(WEP)protocol,which is described in IEEE802.11stan-dard and802.11b standard as the encryption protocol and authentication protocol.After summarizing most kinds of the flaws ,we bring forward two solutions to make up them and improve the security of WLAN.One,which demands little modification of the current infrastructure of WLAN,is an improved temporary solution.The other one is completely new,which applies to the new-built infrastructure of WLAN. |
