摘　　要：由于无线局域网中的移动设备计算能力相对要弱,针对采用IPSec解决无线局域网安全的解决方案,本文提出采用基于对称密码体制的第三方认证来解决WLAN中无线工作站和无线接入点之间的身份认证和密码协商。该方案计算量小,能很好地适应无线局域网自身的特点。The paper analyses the security solutions to WLAN. Because the calculation capability of the mobile equipment in WLAN is relatively weak, the paper presents the scheme of the third party authentication based on the symmetric cryptosystem to solve the identity authentication and key exchange between STA and AP in IPSec. The plan has small calculation quantity, and can satisfy the characteristics of WLAN.
