Since group communication is an upcoming technology, research on secure multicasting has been attracting wide attention. In this context, the already proven PLEASE, p' LEAder SElection model has much to contribute to the security and key management of the multicast group communication. In this paper, the PLEASE model is mathematically compared with other well-known group key management protocols like...
Grid computing has been cited as one of the potential technologies that can offer mammoth computing power in the future. The greatness of grid technology lies in the efficient harnessing of idle resources of the distributed environment, leading to better resource utilization. Security is one of the key aspects of the grid technology. Secure group communication in the grid is a promising area with...
A multicast service network offering QoS for its heterogeneous receiver is taken care by adopting DiffServ framework. In such a network, the network traffic would increase with new receivers joining dynamically without any new senders added. This would affect the QoS of the existing traffic in the network. For this, we propose to integrate a probe based endpoint admission control algorithm along with...
