Abstract
Smart Grid – an intelligent connected grid consisting of millions of smart devices, used to collect data from the grid to improve the efficiency of its operation. These smart devices communicating wirelessly are susceptible to attacks and hence the security and privacy of the smart devices along with the smart grid is a major challenge. Blockchain-based systems provide improved security and privacy and hence gained a lot of attention in the recent past. This paper proposes a blockchain-based architecture for Neighborhood Area Networks (NANs) and Home Area networks (HANs) in Smart Grid. The paper presents a security analysis in terms of confidentiality, integrity and availability to show that the proposed blockchain-based Smart Grid architecture is secure. Also, the impact of the improved security on packet delays, energy and computational overhead is discussed.
