Abstract Smart grid has been acknowledged as the next-generation intelligent network that optimizes energy efficiency. Primarily through a bidirectional communication channel, suppliers and users can dynamically adjust power transmission in real time. Nonetheless, many security issues occur with the widespread deployment of smart grid, e.g., centralized register authority and potential Distributed-Denial-of-Service (DDoS) attack. These existing problems threaten the availability of smart grid. In this paper, we mainly focus on solving some identity authentication issues remained in the smart grid. Combined with blockchain, Elliptic Curve Cryptography (ECC), dynamic Join-and-Exit mechanism and batch verification, a reliable and efficient authentication protocol is proposed for smart meters and utility centers. Simultaneously, the provable security of this protocol is assured by the computational hard problem assumptions. Experiment results show that our protocol has achieved security and performance improvement compared with the other ECC related schemes.

same time. In traditional power grid, the conventional resources (e.g., gas, oil, coal) are continuously used for power generation. The consumption of fossil energy resources brings out many problems, such as rarely high cost, more and more carbon dioxide (CO2 ) emission and environment pollution. Thus, renewable energy resources, such as wind energy, solar energy and tide energy, become significant options to satisfy the increasing requirements of power consumption. Unfortunately, since the traditional power grid is a one-way interaction system, the power plant can not obtain useful feedbacks from users to adjust the power supply strategy in time. Recently, along with the advent of smart grid (SG), the aforementioned problems existed in the electric power industry for a long period could be
