Framework for Providing Security and Energy saving Using Elliptic Curve Cryptography in Wireless Sensor Networks

In this recent years wireless sensors attracted the wireless sensor networks due to the significant advances in minimization. Wireless sensor networks consist of autonomous sensor nodes attached to one or more base stations. Wireless networks of low-power sensing devices are poised to become a ubiquitous part of the computing landscape. As Wireless sensor networks continues to grow, they become vulnerable to attacks and hence the need for effective security mechanisms. Due to these well accepted limitations, WSN is not able to deal with traditional cryptographic algorithms and symmetric based cryptographic schemes don’t scale well when the number of sensor nodes increases. Sensor nodes should be resilient to attacks. Since WSN suffer from many constraints including low battery life, lower processing power, small memory and wireless communication channel. In this paper we propose an energy efficient secure framework that proves the integrity, authentication, and also provides secure communication among the sensor nodes by using the public key algorithm.
