In this study, we propose a novel key management model for localized mobile groups that employ multicasting. The service provisions will not be interrupted while users move among different wireless network areas, while each network provides the may multicast services independently. All the mobile users in a given area form a cluster managed by an area key distributor (AKD) [1], and the AKD takes charge of the distribution of a key and updates the clustersillo.
