Problems solved by technology

[0003] However, the user terminal does not have the verifiability of the SSID of the AP. Therefore, if criminals set their own WLAN AP to the same or similar SSID name as the operator, such as "ChinaUnicom", "CMCC", etc., and the user terminal Judging and accessing the WLAN network only through the SSID, it is easy to be induced and connected to the disguised AP. Therefore, the security of the user terminal is difficult to guarantee, and it may be attacked and cause data loss or paralysis of the terminal system.

Embodiment Construction

[0042] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0043] Since the WLAN access methods of various operators are similar, APs in a certain area broadcast, and the broadcast content usually includes the SSID of the AP in the area and the MAC address of the AP. The user terminal discovers the broadcast SSID and the user confirms that it is associated with a certain SSID. After accessing the AP, the ...

Abstract

The invention provides an access point authorizing method, device and system. The access point authorizing method comprises the following steps of: receiving an authorization request message sent by a communication service platform, wherein the authorization request message comprises an SSID (Service Set Identifier) and an MAC (Media Access Control) address of an access point (AP) to be accessed of a user terminal; determining whether the MAC address of the AP is a legal MAC address resource corresponding to the SSID; if yes, returning an authorization passing response message to the communication service platform to ensure that the communication service platform sends the authorization passing response message to the user terminal. According to the invention, the user terminal authorizes an authorization request of legality of the AP to be accessed, which is initiated by the communication service platform, and an authorization passing result is returned to the user terminal through the communication service platform, therefore the guarantee is provided for accessing the safety AP to the user terminal.

Description

technical field [0001] The present invention relates to communication technology, in particular to an access point authentication method, device and system. Background technique [0002] Wireless local area network (Wireless Local Area Networks, WLAN for short) is an important technology for wireless broadband access. Currently, many operators provide WLAN business services. With the promotion of WLAN services by operators, WLAN access points (Access Point, AP for short) are deployed in more and more areas, and the APs in this area mark the service set identifier (Service Set Identifier, SSID for short) conducts open broadcasting. After the user terminal discovers the SSID, if it confirms access to the SSID, it will associate with the AP of the SSID, that is, the user terminal can access the AP to perform related network application services. [0003] However, the user terminal does not have the verifiability of the SSID of the AP. Therefore, if criminals set their own WLAN...
