A Practical Byzantine Fault Tolerance Blockchain for Securing Vehicle-to-Grid Energy Trading

The impending advancement in the vehicle-to-grid technology (V2G) enables the transmission of information between them and the transfer of energy from battery-powered electric vehicles (EV) to the grid. Confidential information about the EV should, however, be transferred securely from one node to another during the information exchange. Additionally, it is important to maintain the privacy of the grid and EV. In view of this, the paper highlights the usefulness of blockchain in securing the energy trading between EV and the grid. A practical byzantine fault tolerance (PBFT) is utilized for achieving the consensus in blockchain network and it states that for the attack to be successful 33% information is to be manipulated. The proposed PBFT based V2G system is tested in different scenarios and the results shows the effectiveness of the proposed PBFT-based blockchain.
