This paper focuses on designing incentive mechanisms for overlay multicast systems. Existing proposals on the problem are no longer able to provide proper incentives when rational...
For an efficient role based access control using attribute certificate in highly distributed computing environments, we use a technique of structuring role specification certificat...
In secure group communications, a key server can deliver a "grouporiented" rekey message [22] to a large number of users efficiently using multicast. For reliable delive...
We consider the problem of securing a multicast network against a wiretapper that can intercept the packets on a limited number of arbitrary network links of his choice. We assume ...
Existing ad hoc routing protocols are either unicast or multicast. In this paper we propose a simple extension to the Dynamic Source Routing Protocol (DSR) to cater for group comm...
