SECURITY SERVICE CONTROL METHOD AND WIRELESS LOCAL AREA NETWORK TERMINAL

A security service control method and a WLAN terminal are provided, and the method includes: stopping a WPI service between a WLAN terminal and an AP when the WLAN terminal creates a security service of an IP layer and/or a layer above the IP layer, wherein the WPI service comprises: encrypting a data link layer message to be transmitted, and decrypting a received data link layer message. After the WPI service is stopped, when the WLAN terminal cancels the security service of the IP layer and/or the layer above the IP layer, the WLAN terminal completes processes of removing association, association, user authentication and key negotiation in turn with the WLAN AP, and uses a session key obtained through the key negotiation to recover the WPI service. The calculating resources can be saved by using the present invention.
