An Efficient Blockchain-Based Authentication Scheme for Energy-Trading in V2G Networks

Vehicle-to-grid (V2G) networks have been emerged as a new technology in the smart grid (SG). These allow two-way flow of energy-trading between electric vehicles (EVs) and charging stations (CSs) SG. EVs are regarded one most effective tools to reduce energy demands. It will bring great impact on our society human life. Thus, during trading CSs, various security, privacy challenges occur V2G networks. Although several proposals proposed, still there many issues like lack integrity, mutual authentication, identity privacy-preservation make system more vulnerable. Researchers used centralized which may act single point failure. So, for deploying secure SG, we propose an scheme having blockchain three communicating parties, i.e., EVs, utility center. The proposed is divided into phases, first, registration process provides second, searching makes key-generation steps faster, third, authentication them network execute transactions using Merkle Root Hash. security analysis result shows that performance evaluation results illustrate has less communication cost computation time compared existing proposals.
