1. a method for building WLAN security system, comprising:

  • (1) whether user triggers WLAN terminal and on all available wireless channels, searches for the WLAN AP equipment of supporting WPS PBC function, in the time searching WLAN AP, be 1 by WLAN terminal judges quantity, if so, and execution step (2);

    Step (1) comprising;

    (11) user triggers a WPS module by the first trigger module of WLAN terminal, calls the first driver module on all available wireless channels, search for the WLAN AP equipment of supporting WPS PBC function by a WPS module;

    (12) in the time searching WLAN AP, the configuration parameter of the WLAN AP searching and the WLAN AP quantity information searching are sent to a WPS module by the first driver module, and configuration parameter comprises;

    SSID and channel;

    (13) judge whether to search 1 WLAN AP equipment by a WPS module, if so, execution step (2);

    (2) triggered the quantity information of WLAN terminal of active searching in the time T before WLAN AP equipment inspection triggers by user, T is for setting constant, and WLAN AP judge whether WLAN terminal quantity is 1, if so, performs step (3);

    Step (2) comprising;

    (21) trigger the 2nd WPS module by user by the second trigger module on WLAN AP equipment, called the quantity information of the WLAN terminal of active searching in the time T before the second driver module inspection triggers by the 2nd WPS module, T is for setting constant;

    (22) by the second driver module of WLAN AP, the quantity information of the WLAN terminal of active searching is sent to the 2nd WPS module;

    (23) judge by the 2nd WPS module whether described WLAN terminal quantity is 1, if so, execution step (3);

    (3) send WPS by WLAN terminal to opposite end WLAN AP and consult request, if both sides consult successfully, set up safety and connect, after connecting, other WLAN terminals connect with WLAN AP successively;

    Step (3) comprising;

    Send WPS by a WPS module of WLAN terminal to the 2nd WPS module of opposite end WLAN AP and consult request, negotiate content comprises;

    cipher mode, WLAN AP sends to WLAN terminal according to this request by wildcard, and both sides are key derivation respectively, sets up safety and connect after consulting successfully.
