Abstract: PURPOSE: An apparatus and method for distributing a group key based on public-keys are provided to use group key and public key values for safely classifying the group key by the join-in and withdrawal request of a user. CONSTITUTION: A group key distribution unit (410) distributes a group key being used in a group, or a new group key. A public key/secret key generation unit (420) generates a server public key and a server secret key before the distribution of the group key. A group key generation unit (430) outputs the group key being used in the group to the group key distribution unit, and generates the new group key to be distributed to other users and outputs to the group key distribution unit. A group management unit (440) joins a new user to a join-in request group, and withdraws a withdrawal user from the relative group.

Abstract: PURPOSE: A synchronization control apparatus for a MBS[Multicast/Broadcast Service] and a method thereof are provided to provide a mobile IPTV service which is based on Wibro and WiFi networks using a macro diversity signal improvement effect. CONSTITUTION: An access network gateway(100) includes a data distribution unit(110) and a synchronization controller(120). The data distribution unit distributes and transmits MBS data which is inputted in the access network gateway to multiple base stations(200-1~200-N). The synchronization controller receives a MBS data packet and generates and provides a synchronization control rule and MBS burst timing data in order to be performed in an upper synchronizer(220) which is included in the base stations. The MBS data packet takes off GRE[Generic Routing Encapsulation] from the data distribution unit and is de-capsulated.
