Energy Efficient Key Pre Distribution Scheme in WSN

Wireless sensor networks have become ubiquitous in the present world of smart technology. With increasing popularity of WSNs in a number of applications brings the major responsibility of making these networks secure. Thus, providing energy efficient security solutions is the need of the hour. In this paper, we propose an energy efficient key pre distribution approach to establish trust among the nodes. This approach takes into account the energy of the nodes and their relative distances from each other while establishing the keys. Moreover, the existing key pre distribution techniques provide very limited or negligible protection against node compromise attack. The proposed scheme can detect node compromise attack without having the need to share a key ring.
