Wireless network safe access method, apparatus and system

The invention discloses a wireless network safe access method, apparatus and system. The method comprises the following steps: an access point (AP) receiving a detection request frame sent by a station (STA), and obtaining a user name, a user password, and the MAC address of the STA which are carried by the detection request frame; and the AP scheduling a white list configured in advance, utilizing the white list to detect whether the user name, the user password and the MAC address of the STA are valid, and feeding a detection request response frame carrying an encryption mode and secret key information back to the STA when detection results are valid. Through the access method provided by the invention, it is not necessary for a user to carry out complex configuration, be aware of which encryption algorithm is adopted by the AP and input a complex WLAN password so that the use of the user is facilitated; and besides, the white list is arranged for detecting the validity of the access user in a binding mode, so that safety of a wireless network can be effectively protected.
