Tree-Based Group Key Agreement Framework for Mobile Ad-Hoc Networks

In this paper we focus on the establishment of the shared key in mobile ad-hoc groups using a contributory group key agreement (CGKA). Based on the comparison results of most suitable contributory group key agreement (CGKA) protocols we propose a new framework for the group key agreement in mobile ad-hoc networks. Theoretical analysis results show that our framework achieves optimal trade-off between communication and computation costs compared to other protocols
