Secure Authentication for Structured Smart Grid System

An important application area for M2M (Machine to Machine) or IoT (Internet of Things) technology is smart grid system which plays an important role in electric power transmission, electricity distribution, and demand-driven control for the energy. To make the smart grid system more reliable and stable, security is the major issue to be provided with the main technologies. In this work, we propose an authentication mechanism between the utility system and the smart meters which gather the energy consumption data from electrical devices in layered smart grid system. Our proposal enhances the smart grid system integrity, availability and robustness by providing security with low overhead.
