A novel, lightweight, and cost-effective mechanism to secure the sensor-gateway communication in IoT

Abstract

Ensuring highest degree of resistance against potential adversaries in Internet-of-Thing (IoT) is still an open challenge, and the prime reason behind this is the computational complexities associated with designing security algorithms and its corresponding transformation between the cloud and Wireless Sensor Network (WSN) via gateway node. Hence, the proposed system develops a lightweight and highly responsive encryption technique to offer minimal resource consumption from the resource-constraint sensor nodes. The significant contribution is also to introduce a novel bootstrapping key mechanism with the unique generation of the secret key to maintain both forward and backward secrecy. The study outcome shows that proposed system is highly practical to offer reduced resource consumption and faster algorithm processing time in the presence of dynamic scenario of IoT.
