Detection of Spoofing attack using Diffie-Hellman and Key Authentication using Elliptical Curve Cryptography

A MANET is an infrastructure less network, which consists of number of mobile nodes with wireless network interfaces. In MANET the communication among the nodes will be in such a way that the nodes dynamically establish path among one another. The popularity of these kinds of networks created security challenges as an important issue. The nature and structure of such networks makes it attractive to various types of attackers. This paper focuses on the spoofing attack which takes the largest probability of occurrence in the ad-hoc networks. We have tried to resolve this issue using Diffie -Hellman technique and also the time and power is shown efficiently by implementing Elliptical Cryptography Curve (ECC) method. The protocol used in this paper for resolving the above issues is Dynamic Source Routing (DSR) based routing mechanism. The simulation results are provided which indicates the packet delivery ratio, routing overhead, throughput, energy and delay.
