Secure and efficient data transfer in AODV routing protocol using RSA encryption

Abstract

Mobile Ad-Hoc Networks (MANETs) are recognised as a key emerging technology for use whenever cellular communications are either infeasible, inefficient, or cost-ineffective. MANETS are composed of nodes that are arranged in a self-organizing manner, without a central device like a switch or router. The nodes communicate with each other over wireless links and cooperate in a distributed fashion. Smartphones are the most ideal network nodes in many scenarios where traditional networks are unavailable, but building a secure network with them is not easy. This paper extensively uses the existing possibilities to build a secure MANET. The designed MANET has been built on an NS3 simulator, with the base protocol being Ad-hoc On-demand Distance Vector (AODV) and message encryption is done by using RSA Algorithm. The Secure AODV protocol extension is implemented using the RSA extension.
