- Abstract
- A home energy management system (HEMS) in a smart grid is installed each household while measuring and gathering real-time consumption of energy such as electricity, water, natural gas. Moreover, the HEMS regularly reports the energy consumption information to the utility provider for monitoring and billing. In a smart grid, the energy unit price can be changed anytime according to the amount of real-time energy consumption. At the same time, the HEMS learns the changed energy unit price in real time. Due to open nature of smart grid networks, however, there are potential security issues, e.g., illegal energy use, eavesdropping, and usage data manipulation. The security issues must be addressed in order to guarantee a safe and secure smart grid service. In this paper, we propose an one-way hash chain based solution for secure and fast billing process between a HEMS and a utility provider. Since the proposed billing protocol requires less computational costs than existing works, it is suited to a smart grid which should deal with a lot of energy-related messages rapidly. Furthermore, the proposed billing protocol provides non-repudiation, confidentiality, message integrity and entity authentication.
