MULTICAST KEY AGREEMENT PROTOCOL FOR MOBILE AD HOC NETWORKSMulticast Key Agreement • July 11th, 2006
Abstract: In this paper we address the problem of Multicast secure data over a multihop wireless ad hoc network. Many protocols that have been proposed are not really convenient for mobile ad hoc networks. We propose a key agreement protocol that aims to solve problems that are specific to ad hoc networks such as mobility, unreliable links, and multihop communication cost. The main idea is to focus on group dynamics and complete node mobility in ad hoc environment to develop an adaptive protocol that is suitable for the network and group changes. Doing so, we extend and adapt the proposed Tree based Group Diffie-Hellman (TGDH) protocol to pure mobile ad hoc network. Our method promotes the use of a fully balanced tree and eliminates the broadcasting of the entire tree as it appears in TGDH. We introduce a probabilistic value that gives the state of group dynamism. We simulated our protocol using C++ code and some results are presented in this paper and currently other simulations are g
