Abstract: This paper describes the process of user authentication and key negotiation brought to WLAN by 802.11i, proposes a new mechanism which is designed based on 802.11i standard and 802.1X standard. The mechanism will provide user authentication and key negotiation in access controller under WLAN split MAC structure. Therefore the system will provide robust security services to the WLAN user.

Key words: access authentication, key negotiation, four-way handshake, split MAC

摘要： 简述了802.11i和802.1X引入无线局域网的用户接入认证与密钥协商过程。提出了在分割式MAC架构的WLAN中如何在接入控制器中实现用户认证与密钥协商机制的设计方案，从而在系统中向用户提供安全可靠的数据传输服务。
