An optimal lightweight cryptographic approach for WSN and its energy consumption analysis

Abstract

Wireless Sensor Network has various security issues like authentication of sensor nodes and its power consumption. Therefore, we are focusing on evaluation and optimization of power consumption in wireless sensor networks using light weight cryptographic techniques. This research paper studies the certificateless cryptographic algorithms and hence develops an optimal algorithm for the same. The proposed algorithm is more efficient and secured by eliminating the concept of digital signature to make the light weight cryptographic algorithm using PKC and IBE. The simulation result shows that the proposed algorithm can achieve approximately 5-20% reduction of energy consumption with same level of security.
