Automatic authentication method, apparatus and system of wireless local area network (WLAN)

Abstract

The invention discloses an automatic authentication method, apparatus and system of a wireless local area network (WLAN), for solving the problem of illegal registration due to easy stealing of authentication information by use of a conventional WLAN automatic authentication technical scheme. According to the method, an AP obtains the MAC address of an STA and carries a second authentication request carrying the MAC address and a password from a first authentication request of the STA to an AC, the AC forwards the second authentication request to an RADIUS server, under the condition that the RADIUS server confirms that a corresponding relation between the MAC address in the second authentication request and a preset password exists in a corresponding relation between a prestored MAC address and the preset password, it is determined that the preset password in the second authentication request is valid, an authentication response carrying authentication validity information is sent to the AP through the AC, and the AP authenticates that the STA is an illegal user in case that the authentication response carrying the authentication validity information is received.

Description

technical field

[0001] The present invention relates to network communication, in particular to a wireless local area network (WLAN, Wireless Local Area Network) automatic authentication method, device and system. Background technique

[0002] WLAN is a technology that uses wireless technology to realize fast access to Ethernet, and can provide local wireless Internet access services. All WLAN adopts a unified deployment method, and its authentication methods are divided into: client-based authentication, network-based (WEB) authentication, and in non-operating or small internal WLAN networks, there are also media access controller-based (MAC, Media Access Controller) The method of address authentication.

[0003] At present, the methods for performing WLAN automatic authentication mainly include the following two methods:

[0004] Method 1. When the access point (AP, Access Point) accesses the WLAN at the station (STA, Station), obtain the MAC address of the STA's media a...
