SECURITY SERVICE CONTROL METHOD AND WIRELESS LOCAL AREA NETWORK TERMINAL

摘要

A security service control method and Wireless Local Area Network (WLAN) terminal are provided, the method includes that: when the security service on Internet Protocol (IP) layer and/or above IP layer is created by the WLAN terminal, the WLAN Privacy Infrastructure (WPI) service between the terminal and the access point is stopped; The WPI service includes that: the data link layer message to be transmitted is encrypted, and the received data link layer message is decrypted. After the WPI service is stopped, and when the security service on IP layer and/or above IP layer is canceled by the WLAN terminal, said WPI service is recovered by completing removing association, association, user authentication and secret key negotiation process with the access point to WLAN in turn, and utilizing the session secret key obtained from negotiation in the secret key negotiation process. The calculating resource can be saved by using the invention.
