Executive Summary

Alterations and unpredictability of the network topology in Mobile Ad hoc NETworks (MANETs) are less capable of ensuring the security of multicast data transmissions than in conventional networks. Despite the recent development of many key agreement protocols for MANETs, to the authors' knowledge, only a few secure multicast data transmissions have been integrated into the key agreement. This paper proposes a Dynamic Multicast Height Balanced Group Key Agreement (DMHBGKA) that allows a user in a multicast group to efficiently and dynamically compose the group key and securely deliver multicast data from a multicast source to the other multicast group users in wireless ad hoc networks.
