Abstract
The present invention relates to a method for managing a group traffic encryption key (GTEK) in a wireless portable Internet system. In the method for higher security of a group traffic service such as a multicast service a broadcast service and a multicast-broadcast service (MBS) a base station periodically generates and distributes a GTEK to a subscriber station served with the group traffic service. A lifetime of a group key encryption key (GKEK) used for encrypting a GTEK is set greater than that of the GTEK. That is the GKEK is updated once while the GTEK is updated several times. According to the present invention security for the group traffic service is increased while reducing radio resource consumption.
