Authentication method and system for wireless local area network terminal

Abstract

The invention discloses an authentication method for a wireless local area network terminal, which comprises the following steps of: receiving a user login authentication information-carried Internet access request message sent by a terminal, by network-side equipment, wherein user login authentication information is generated and transmitted to a terminal to be stored by the network-side equipment when the previous login of the terminal is successful, and comprises user information and an authentication-free period; applying the user information in the received user login authentication information to authenticate the terminal when the network-side equipment judges that the terminal is just within the authentication-free period according to the authentication-free period in the received user login authentication information; and the network-side equipment sends a successful authentication message to the terminal after the authentication is successful. When the authentication method and system are adopted, the problem of low authentication efficiency caused by needing a user to repeatedly input a user name and a password in the authentication process of a wireless local area network in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of wireless local area network, in particular to a method and system for authenticating a wireless local area network terminal. Background technique [0002] In the current Web authentication mechanism of the Wireless Local Area Network (WLAN), an important authentication method is Portal authentication, which is usually also called Web authentication, and a website authenticated by Portal is generally called a portal website. When an unauthenticated user surfs the Internet, the device forces the user to log in to a specific site, where the user can access services for free. Traditional access control methods such as 802.1x and PPPoE require the cooperation of the client and can only control user access at the access layer. The Portal authentication technology provides a flexible access control method, which can implement access control at the access layer and at the entrance of key data that needs to be pr...
