Description
Summary: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 wire- less network areas, while each network provides the respective 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 clusters accordingly. In our model, a special security coprocessor （SC） is em- bedded in the mobile client to facilitate the secure calculation of a group key. After receiving rekeying information, a mobile device calculates the group key entirely on the client side, which avoids the direct transmission of the key.
