Dynamic Key Exchange Protocol for Security In Wireless Networks

Abstract

In today`s world of advanced wireless communication, authentication of a message is a huge research challenge. An appropriate solution of this problem is Cryptographic hash function. Some of the most popular Cryptographic hash functions are MD5 and SHA1. However, these commonly used Cryptographic hash algorithms require huge computational energy which is not affordable by energy starved networks e.g. Wireless Sensor Networks(WSN). In these application of wireless communication, major constraints like communication and computation overhead require high energy which is generally not affordable. So, keeping this fact in mind in this project work a light weight, one way hash algorithm is designed producing a small length hash digest especially for these energy starved networks. The main aim of the work is to make the algorithm light weight so that when networks like WSN uses this then each node can successfully run the algorithm with low energy. This proposed algorithm is developed using MATLAB simulation and the results were compared with conventional algorithms.
