Group rekeying with limited unicast recovery
In secure group communications, a key server can deliver a “group-oriented” rekey message [16] to a large number of users efficiently using IP multicast. For reliable delivery, Keystone [17] proposed the use of forward error correction (FEC) in an initial multicast, followed by the use of unicast delivery for users that cannot recover their new keys from the multicast. In this paper, we investi...

In secure group communications, a key server can deliver a ‘‘group-oriented’’ rekey message [C.K. Wong, M.G. Gouda, S.S. Lam, Secure group communications using key graphs, in: Proceedings of ACM SIGCOMM 98, September 1998, pp. 68–79] to a large number of users efficiently using multicast. For reliable delivery, Keystone [C.K. Wong, S.S. Lam, Keystone: a group key management system, in: Proceedi...

Srinath R. Joshi. Packet Loss Recovery for Unicast Interactive Video Transmission over the Internet. (Under the direction of Professor Injong Rhee.) The current Internet is not reliable; packet loss rates are frequently high, and varying over time. Transmitting high-quality interactive video over the Internet is challenging because the quality of compressed video is very susceptible to packet l...
متن کاملReducing Frequency of Group Rekeying Operation
In the past, Ad-hoc networks were used in limited areas which require secure group communication without Internet access, such as the army or emergencies. However, Ad-hoc networks currently are widely used in variety applications like group chat, smart applications, research testbed etc. Ad-hoc network is basically group based network in the absence of access point so it is prevalent to provide...
متن کاملScalable Rekeying limited to Subgroup using Hybrid Key Trees
Maintaining security is a critical issue in any group communication protocols. The objective of security in a group communication is to ensure the access only to the legitimate members of the multicast group. The entry and eviction of the members are the main criteria to change the group key and to give them more assurance of a secret communication, which is known as re-keying. Since it is a fr...
