Secure authentication approach using Diffie-Hellman key exchange algorithm for WSN

A wireless sensor network consist several sensor nodes, which are resource constraints device with low processing, energy and storage capabilities. WSN can be used to measure and monitor many challenging problems and typically involve in monitoring and controlling areas such as battlefield monitoring, object tracking etc. In Wireless sensor network security and economy of total energy are two important and necessary aspects; node to node authentication is a crucial service in WSN that ensure security. This paper propose an node to node authentication protocol with the concept of cryptography and cluster head that resolve the weakness of Diffie-Hellman key exchange scheme. The Performance of the proposed solution has been evaluated and simulated to provide a better network performance.
