A Confidentiality Scheme for Energy Efficient LEACH Protocol Using Homomorphic Encryption
Wireless Sensor Network (WSN) has been an active research area over the past few years. However, the salient limit is energy. Due to this limitation, it seems important to design a routing protocol for WSN so that sensing data can be transmitted to the receiver securely and efficiently and at the same time energy consumed must be minimum. Hence there is a need to develop a confidentiality scheme for energy efficient Leach protocol (hierarchical clustering protocol) using homomorphic encryption. In homomorphic encryption, data can be aggregated algebrically without decryption and hence less energy consumption.
