METHOD FOR CONTROLLING SECURITY OF WIRELESS LOCAL AREA NETWORK USING DYNAMIC RE-KEYING

摘要

PURPOSE: A method for controlling security of a wireless LAN using dynamic jacking is provided to reduce a load of a server by using a re-authentication process and a process of redistributing a secret key through a wireless LAN communication system. CONSTITUTION: An initial authentication process and an initial security process are performed between a client terminal(10), a TTLS(Tunneled Transport Layer Security) server(18), and an AAA(Authentication Authorization Accounting) server(20). A new master secret key is generated by using the initial authentication process and the initial security process of the authentication/security server. A data encryption key for data security is generated from the new master secret key. The generated data encryption key is transmitted to the client terminal.
