Designing a Model for Energy Efficient and Secured Data Communication Using RSA Algorithm in Wireless Sensor Networks

Sensor network is used in various military applications which demand protection against eavesdropping. Therefore some sensor networks need secured data communication from sources to base stations. As sensor networks adopts multihop routing from sources to the base station, and that there are no central authority in between, securing such a network is challenging. In this work we first propose a clustering based technique for routing. Clusters are dynamically formed before every round of transmission. Every cluster has a cluster head which can manage the keys locally. as every cluster has independent time schedule, public key cryptography with symmetric keys is essential. Therefore we use RSA algorithm along with RSA based system for a secured sensor network.
