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 term

Example Embodiment

[0055] First, the first embodiment of the method of the present invention is introduced:

[0056] In this embodiment, the SSID is hidden in the Beacon frame broadcasted by the AP device to each wireless terminal, and the wireless terminal searches for the SSID through the Probe Request method.

[0057] Refer to Figure 3, which is a flowchart of the first embodiment, including:

[0058] Step 301: The wireless terminal sends a Probe Request, requesting ProbeResponse including SSID, etc.;

[0059] Step 302: The AP device responds to the Probe Request of the wireless terminal and feeds back the ProbeResponse containing the SSID;

[0060] Among them, Probe Response includes the basic information of the BSS to which the AP belongs and the basic capability level of the AP.

[0061] In actual applications, due to the strength of the signal, it is very likely that there is a situation where the neighbor AP also feeds back Probe Response to the wireless terminal, and the feedback signal is ...

Example Embodiment

[0070] The following describes the second embodiment of the method of the present invention:

[0071] Unlike the hidden SSID of the Beacon frame in the first embodiment, the Beacon frame in this embodiment carries the SSID. The wireless terminal learns the SSID and other information by listening to the Beacon frame broadcast by the AP device. When the terminal prohibits access notification, a mismatch notification is sent to the wireless terminal to inform the wireless terminal that the SSID used by the wireless terminal does not match and cannot successfully log in to the network, so that the user can use other SSIDs to access the WLAN, and avoid the user from complaining without knowing.

[0072] Refer to Figure 4, which is a flowchart of the second embodiment, including:

[0073] Step 401: The AP device broadcasts a Beacon frame carrying the SSID;

[0074] Step 402: After listening to the Beacon frame, the wireless terminal requests authentication from the BRAS or AC controller...

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...
