Wireless network safe access method, apparatus and system

Abstract

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.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a wireless network security access method, device and system. Background technique [0002] WLAN (Wireless Local Area Network, wireless local area network) technology is one of the hotspots in today's communication field. Compared with wired, the start-up and implementation of wireless local area network is relatively simple, and the maintenance cost is low. Generally, only one or more access point devices need to be placed A local area network covering the entire building or area can be established. In a typical wireless network system, STA (Station, station) refers to a terminal such as a PC or a portable notebook computer with a wireless network card, and an AP (Access Point, access point) provides a bridge function from a wireless client to a LAN. Wireless-to-wired and wired-to-wireless frame conversion is performed between the wireless client and the wireless...

Problems solved by technology

[0005] However, due to the open characteristics of wireless LAN channels, any of the above encryption methods has certain defects. For example, when enough data packets are obtained, the encryption method will be cracked; through SSID scanning software, hidden SSIDs can be found, etc. Wait

It can be seen that whether it is the WEP, WPA, WPA2 encryption methods proposed by IEEE, or the WPS encryption method proposed by the Wi-Fi Alliance, or the solution proposed by the patented technology, there are problems such as complicated operation process and easy leakage of encryption methods and other problems. defect
