摘　　要：为了提高无线局域网的安全性,解决传统安全机制WEP协议中所存在的缺陷,给出了一种基于IEEE802.11i的无线局域网安全模型。在分析了IEEE802.11i协议的体系结构和安全机制的基础上,对IEEE802.11i的数据加密技术进行了剖析,详细分析了TKIP和CCMP协议的加解密过程和安全性能,结果表明,TKIP的安全性能仍有局限性,只是一种过渡方案,而CCMP才是健壮的数据保密协议。In order to improve the security of wireless LAN and solve the flaws of security mechanisms based on WEP,a security model based on IEEE802.11i protocol of WLAN is proposed.After the structure of IEEE802.11i protocol and security mechanisms are analyzed,the standard of IEEE802.11i in data encryption is also dissected,and the encryption-decryption process and security of TKIP and CCMP are introduced in detail.The result indicated that the security of TKIP still has limitations,it is only a kind of transitional scheme,and the CCMP protocol is still robustly.
