An Efficient and Secure Group Key Agreement Using in the Group Communication of Mobile Ad-hoc Networks

In mobile ad-hoc networks, secure group key management is an increasing popular research area to explore. This paper presents a group key agreement designed to provide efficiency and security in mobile ad-hoc networks, addressing complexity, security, and authentication issues of this agreement. This proposed agreement is independent of the network topology and can ensure secure group communication. Based on efficient local contributory cluster key menagement and gateway nodes, it is nicely suitable for the inherent characteristics of mobile ad-hoc networks such as independent, mobility, and unreliable links, etc. Eight group membership operations are presented including initialization join, mass join, merge, leave, mass leave, partition, and key refresh.
