Method and device of access point equipment for preventing error access

Abstract

The utility model discloses a method for guarding against the misconnection to the AP equipment. After the wireless terminal requires for the certification from the network via the AP equipment, the network will examine the validity of the wireless terminal. When the certification fails, the network equipment will record the illegal frequency of the wireless terminal's misconnection to the AP equipment. When the illegal frequency reaches the preset threshold, the network equipment will send the signal to the AP equipment for forbidding the wireless terminal access. After the signal is received by the AP equipment, the response t the wireless terminal is forbidden. The utility model can be used to effectively prevent the disabled user's access to the AP equipment. As the frequency of misconnection is arranged and dynamically adjusted, the influence to the user operation can be reduced, so as to lower the frequency of connect failure and the user's complains. As responding to the above method, the utility model also provides a device used for guarding against the misconnection to the AP equipment.

Description

technical field [0001] The present invention relates to the field of wireless local area network (Wireless LAN, WLAN) security technology, in particular to a method and device for preventing wrong access to access point (Access Point, AP) equipment. Background technique [0002] Due to the open transmission medium of wireless communication, the security performance of WLAN has always been the focus of attention. The currently established WLAN security mechanism mainly includes three aspects: service set identifier (Service SetIdentifier, SSID) mechanism, physical address (MAC) filtering control mechanism and the Wired Equivalent Privacy (WEP) mechanism, which will be introduced respectively below. [0003] 1. SSID [0004] In WLAN, different SSIDs are firstly configured for multiple access points, and wireless terminals must know the SSIDs in order to send and receive data in the network. If a mobile terminal attempts to access the WLAN, the AP first checks the SSID of the...

Problems solved by technology

At the same time, the AP and all the wireless terminals connected to it use the same key, and the users who use the same AP also use the same key, so it will bring the following problems: once the key of one of the users leaks, the keys of other users can't keep it secret

For example: two wireless terminals that are very close to each other belong to different APs, but in the process of searching for APs in the above step 201, since the SSID of the neighbor wireless terminal is the same as that of the neighbor wireless terminal, it is very likely to search for the neighbor AP, then, it will automatically try Connect to the neighbor's AP, but because the operator has bound the ADSL port, user name and password, the wireless terminal cannot access the WLAN through the neighbor's AP

[0023] As analyzed above, it is possible to prevent others from accessing the AP through MAC address filtering and WEP encryption. However, both of these methods require manual configuration by the user, which is very cumbersome. It is also inconvenient to configure
