Securing AOMDV protocol in mobile adhoc network with elliptic curve cryptography
Jeenat Sultana, Tasnuva Ahmed · 2017
Mobile Adhoc Network (MANET) is comprised of mobile nodes where each mobile node acts as both router and terminal. While acting as a router a reliable routing protocol is chosen ensuring the packet to reach its destination and an agent is responsible for the transmission of packet while acting as a terminal. In this paper, we implemented secure packet transmission in mobile adhoc network (MANET) through Adhoc On Demand Multipath Distance Vector (AOMDV) routing protocol. AOMDV, a multipath extension of AODV (Adhoc On Demand Distance Vector) routing protocol, is more reliable than its parent protocol, though not completely restraint from attacks. To keep the packets secure in an adversary environment with multiple attackers is the main objective. Elliptic Curve Cryptography (ECC) has been chosen to secure the packets against blackhole attack. Elliptic Curve Cryptography provides security with smaller key size compared to other public-key encryption. We configured three different types of environment using NS-2.35 which is a discrete event network simulator; a secure environment without malicious activity, a hostile environment with blackhole attackers and with ECC implementation by the agent and analyzed their performance.
