In this paper we deal with the problem of an owner sending a message to a group of users such that some subset of users is considered revoked and should not be able to obtain the content of the message. We concentrate on the stateless receiver case, where the users do not update their state from session to session. Many broadcast encryption protocols require handshaking for the contents sharing. In...
In recent years active reliable multicast protocols have gained popularity. However, the existing active reliable multicast protocols are based on receiver-initiated approach for loss recovery. Our approach, named DHARM, distributes the responsibility of loss recovery between the sender and the receivers. It helps to solve the scalability problems like acknowledgement implosion, recovery load balancing...
IP multicast plays a very important role in group communication. At the network level IP multicast provides an efficient one-to-many IP packets delivery but without providing any reliability guarantees. Desirable features of reliable multicast include low end-to-end delay, high throughput and scalability. Active networks open a new perspective in providing more efficient solutions to the problems...
