An Interval-based Contributory Key AgreementContributory Key Agreement • September 10th, 2011
Applications in Dynamic Peer Group are becoming in- creasing popular nowadays. There is a need for security services to provide group-oriented communication privacy and data integrity. It is important that members of the group can establish a common secret key for encrypting group communication. A secure distributed group key agreement and authentication protocol is required to han- dle this issue. A key tree approach has been proposed by other authors to distribute group key in such a way that the rekeying cost scales with the logarithm of the group size for a join or leave request. The efficiency of this key tree approach critically depends on whether the key tree remains balanced over time as members join or leave. Instead of performing individual re-keying operations, an interval-based approach of re-keying is adopted in the pro- posed scheme. The proposed interval based algorithms considered are Batch algorithm and the Queue-batch al- gorithm. The interval-based approach provides
