A Novel Lightweight Authentication for Intelligent Energy Monitoring in Smart Home

Abstract

The widespread acceptance of IoT-based application is increasing exponentially day by day. The smart home is one of the key applications of an IoT in which the smart appliances are connected with the smart meter. A smart meter collects the energy consumption data at a particular interval and sends those data to the smart home users and an electricity controlling center. The secure authentication and key establishment between the user and smart meter provide secure transmission of energy consumption data. In this paper, we propose an authentication and key exchange mechanism between the smart home user and the smart meter via a gateway node using elliptic curve cryptography. The formal security analysis of the proposed scheme is performed using a real-or-random model, and informal security analysis is given based on a widely adopted Dolev–Yao channel. An implementation of the proposed protocol is performed using a publish–subscribe-based MQTT protocol. At last, we discuss a performance analysis and comparison of the proposed scheme with the other existing schemes.
