| 1. An apparatus for managing a group transient key (GTK) in a wireless local area network (LAN) system, the apparatus comprising:
a GTK generation timing deciding means for determining a time to generate a GTK based on a security state of a mobile station;
a GTK generating means for generating a GTK in accordance with the time determined by the GTK generation timing deciding means;
a GTK exchanging means for exchanging the GTK generated by the GTK generating means with the mobile station based on the security
state of the mobile station; and
a GTK setting means for setting the GTK after the GTK is exchanged with the mobile station.
