Abstract: Firstly, this article simply analyzes the security of 802.11 WLAN. Secondly, simply introduces the characters of WLAN based on 802.1x. This article mainly focuses on the design of a security management protocol based on password which is suitable for small system. In this proposed scheme the mobile user and the access point can be authenticated respectively, the session key can be dynamically distributed between them in a secure way. In addition, the management of users is very convenient.
