[0022] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0023] A WLAN contains at least one wireless access point AP and one user (client). The WPA / WPA2-PSK authentication process is a four-step handshake process. The client generates a verification value MIC through the input key, AP name (SSID), user MAC address, random number Nonce and other data and sends it to the AP. Compare with the stored correct MIC value, if they are consistent, the identity authentication will be passed, otherwise it will be rejected. The main difference between WPA and WPA2 is that WPA uses the HMAC-MD5 algorithm in the last step of generating the MIC value, while WPA2 uses the HMAC-SHA1 algorithm. Therefore, the method of the present invention is applicable to WPA and WPA2.
