“A novel approach using elliptic curve cryptography to mitigate Two-Dimensional attacks in mobile Ad hoc networks”

Abstract

Abstract The “Mobile Ad Hoc Network” (MANET) can change locations configure itself in hover, as this technology uses the wireless connections to connect the numerous networks over glide. However, MANET is prone to security attacks such as Blackhole, Wormhole, Jellyfish, and Denial-of-Service Attack (DoS) attacks. In these attacks, the malicious nodes guarantee that they have the briefest way to the destination. At the destination, in the wake of getting the information bundles, possibly, they drop the packet or send an inappropriate message to the source called wormhole and Blackhole attacks. This paper proposes a protocol to mitigate the wormhole attack and black hole attack. The proposed protocol is a combination of scalable-dynamic elliptic curve cryptosystem and AODV protocol, termed as ECCAODV. We have considered two-dimensional vector function F [A, B] where A is Wormhole Attack, and B is a Blackhole attack. For verifying our proposed protocol, we have considered two scenarios first without attack, and the other is with the attack. When there is no attack, we have represented that as AODV in graphs, and with the attack, we have described it as MAODV. We have applied our proposed method, i.e., ECCAODV on attack scenario, and we got improved results in terms of throughput, packet delivery ratio, end to end delay, shows the improvement and found to be 1226.19 kbps, i.e., enhancement of 130.95% and delay decrease of 40% from MAODV. Besides, two more critical parameters are investigated in detail, such as energy consumption and routing overhead. It has been observed that ECCAODV, in-turn resulting in better results with minimum energy consumption saving of 75.97% as compared to the attacked scenario and 64.01% difference of routing overhead over the MAODV. Therefore, the proposed protocol paves the way and possesses the potential to safeguard the MANET.
