Distributed Collaborative Key Agreement Protocol for Dynamic Peer Groups

In recent years, group-oriented applications and collaborative protocols are gaining popularity. This calls for group key management which forms the basic building block in achieving secure group communication. The points that differentiate it from the traditional communication are that they do not have a centralized server but a distributed system, group key being contributory and dynamic nature wherein members can join and leave the group when required. The group key management requires for function such as join, leave along with the concept of rekeying. The group key is recomputed every time a member adds or leaves the group .The work in this paper provides a fundamental understanding about establishing a group key via a distributed and collaborative approach for a dynamic peer group.[1].
