Method for carrying out access authentication through monitoring client spectrum field intensity

Abstract

The present invention discloses a method for carrying out access authentication through monitoring client spectrum field intensity. The method comprises the following steps that: firstly, a client opens WLAN wireless access, searches the SSID of a wireless access point broadcast and initiates an association request, a wireless access point returns successful association information and records the MAC address of the client; and then the client approaches the wireless access point, the wireless access point automatically monitors the field intensity in a specified spectrum emitted by the client, when the spectrum field intensity reaches or exceeds a preset threshold, the wireless access point writes the MAC address of the client into a legitimate MAC address list, the authentication of the client is passed, and the normal Internet access is available. According to the method, the requirement of client authorized access is low, and the simple authorized Internet access of the client can be realized without the special function of the client.

Description

technical field [0001] The invention relates to the field of wireless technology, in particular to a method for performing access authentication by listening to the spectrum field strength of a client. Background technique [0002] When a client accesses a wireless access point that requires authorized access, the client generally needs to provide a password to access, but when the password is artificially leaked or shared, the authorization of the access point will become invalid, making the access point The security of the point is reduced. [0003] In the prior art, the authorization validity of the access point is generally ensured through fixed or dynamic passwords, coupled with MAC address restrictions, etc., but these methods increase the functional requirements and operational complexity of the client, and the user Configuration is required to take effect. Contents of the invention [0004] In order to overcome the shortcomings of the above-mentioned prior art, t...
