A Matrix-Based Pair-Wise Key Establishment for Secure and Energy Efficient WSN-Assisted IoT

Abstract

The Internet of Things (IoT) is getting the reputation as one of the most optimistic networking paradigms that is reducing the gap between the cyber world and physical world. Most of the participating nodes in IoT network are sensors, which are limited in terms of resource such as energy, computation power, memory and so on. In IoT network, nodes communicate with each other via wireless medium, which makes the IoT network vulnerable to many security threats including eavesdropping. The IoT network is deployed in a large area and work on 24/7 hours, so an energy efficient scheme is one of the major issues in IoT. To achieve secure and energy efficient network, this article contributes: (1) A hierarchical topology for IoT network deployment; (2) symmetric matrix-based pair-wise key generation for secure communication; (3) A secure and energy efficient secure routing algorithm for the proposed model.
