EETSS: Energy Efficient Transitive Signature Scheme for Secure Group Communication in MANETs
Boopathi Gopalakrishnan, A. Shanmugam, Bannari Amman · 2013
A secure group communication in Mobile Ad-Hock Networks is challenging due to the mobility and limitations in computational and battery power of the nodes. This can be achieved by multicast routing protocol that ensures security through key management schemes. In this paper we proposed an energy efficient multicast routing protocol to establish the group in MANETS. In order to preserve security in data transmission, transitive signature scheme was introduced to enhance the security among the group nodes. The nodes may join/leave the group dynamically. To achieve this, the rekeying operation is performed for every change that happens in the group. The performance analysis on computational and communicational cost is done by varying group size and energy level of the nodes. This scheme results in low computational cost with respect to other protocols. Keyword- Energy efficient Multicast Routing Protocol, Secure Group Communications, Transitive Signature scheme, MANET. I. INTRODUCTION A Mobile Ad-hoc Network (MANET) is a system of wireless mobile nodes that dynamically self-organize in arbitrary and temporary network topologies. In mobile ad hoc network, nodes can directly communicate with all the other nodes within their radio frequency range; whereas nodes that are not in the direct communication range use intermediate node(s) to communicate with each other. In these two situations, all the nodes that have participated in the communication automatically form a wireless network, therefore this kind of wireless network can be viewed as mobile ad hoc network. These properties make MANET very suitable for group communications. This document is a template. An electronic copy can be downloaded from the conference website.
