Analysis of energy efficient ECC and TinySec based security schemes in Wireless Sensor Networks

Modern day scientific society has seen the emergence of various trends in research and implementation. Wireless Sensor Network (WSN) is one among those research trends that has emerged, but its progress has been dammed by the security concerns due to certain limitations in resource and energy scarcity. In this paper we have analysed the performance of certain common well known security schemes like TinySec, RC5, ECIES and ECDSA by implementing it in real time scenarios. We have made a detailed comparison among them to find out their affectivity and their performance under multiple metrics. The paper also promotes the use of a security scheme based on Elliptical Curve Cryptography (ECC), utilizing ECDSA and Diffie-Hellman (DH key transfer). Analysis results shows that the scheme works better than the common existent schemes and is also energy efficient as well as can conserve resources if used appropriately.
