A Security Enhancing Scheme in Leach using Homomorphic Encryption

Neha Chhabra, Parikshit Singla

Abstract: As WSNs grow in application area and are used more frequently, the need for security in them becomes inevitable and vital. However, the inherent characteristics of WSNs incur constraints of sensor nodes, such as limited energy, processing capability, and storage capacity, etc. These constraints make WSNs very different from traditional wireless networks. Consequently, many innovative security protocols and techniques have been developed to meet this challenge. In this paper, we outline security and privacy issues in sensor networks, address the state of the art in sensor network security and energy consumption of different scheme; specially application of public key cryptography also known as homomorphic encryption. Till now it is a known fact that asymmetric key cryptography is not suitable for WSN. But with the introduction of new energy efficient sensor nodes such as TelosB etc. researchers are exploring and evaluating the effect of public key cryptography on WSN.
