Scalable 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...
متن کاملGroup 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...
متن کاملBatch Rekeying in Mykil Key Management System
This paper describes support for batch rekeying in Mykil, a key management system for supporting secure group multicast. Batch rekeying in Mykil allows for substantial reductions in the cost and complexity of rekeying operations, arguably the expensive portion of the system. By accumulating join and leave operations and utilizing an algorithmic approach to minimize the number of necessary rekey...
متن کاملGroup rekeying with limited unicast recovery q
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...
متن کاملA Scalable and Reliable Key Distribution Protocol for Multicast Group Rekeying
Scalable group rekeying is one of the important problems that needs to be addressed in order to support secure communications for large and dynamic groups. One of the challenging issues that arises in scalable group rekeying is the problem of delivering the updated keys to the members of the group in a reliable and timely manner. In this paper, we present a new scalable and reliable key distrib...
