V2G Charging and Discharging Information Authentication Based on Blockchain Technology

Currently, traditional Public Key Infrastructure (PKI) technology faces issues such as single points of failure and cumbersome certificate management in security authentication. The decentralized and tamper-proof characteristics of blockchain technology can provide feasible solutions to these problems. Therefore, this paper proposes a blockchain-based Vehicle-to-Grid (V2G) charging and discharging information authentication scheme. First, the background and significance of this study are explained, highlighting the importance of integrating blockchain with V2G. The system architecture for V2G charging and discharging information authentication based on blockchain technology is then designed, and the security requirements of the system are analyzed. Subsequently, to address the security issues present in the system, a blockchain-based information authentication scheme is proposed, which includes the design of vehicle charging and discharging information authentication and the design of the blockchain for vehicle charging and discharging information. This effectively ensures the security and accuracy of user information. Finally, the security of the proposed scheme is evaluated, and the results indicate that the proposed scheme meets the security requirements for V2G charging and discharging information authentication.
