Modified master key based multipath reinforcement pre-distribution scheme for wireles sensor networks

Abstract

Wireless Sensor Network (WSN) is one of the budding fields of technology. It is mainly used for Environmental monitoring and Data accumulation. Due to the limited energy in WSNs, it faces many practical difficulties. The main challenge is the security issues. Objective of this project is to provide security against clone attack in a WSN that are arranged in cluster topology. In this paper, a method to implement three important security measures namely i) Master – Key Pre-distribution solutions, ii) Super imposed disjunct matrix code and iii) Multipath key reinforcement scheme is discussed. One method complements the advantage of other method and thus provides high security. The final analysis shows that the computational overhead is minimum.
