A Secure Energy Internet Scheme for IoV Based on Post-Quantum Blockchain

Abstract

With the increasing use of distributed electric vehicles (EV), energy management in the Internet of vehicles (IoV) has attracted more attention, especially demand response (DR) management to achieve efficient energy management in IoV. Therefore, it is a tendency to introduce distributed energy such as renewable energy into the existing supply system. For optimizing the energy internet (EI) for IoV, in this paper, we introduce blockchain into energy internet and propose a secure EI scheme for IoV based on post-quantum blockchain, which provides the new information services and an incentive cooperation mechanism for the current energy IoV system. Firstly, based on the principles of constructing a short lattice basis and preimage sampling, a lattice signature scheme is proposed and used in blockchain for authentication, which provides anti-quantum security. Secondly, we design the EI based on the post-quantum blockchain model. Lastly, based on this model, we design a secure EI scheme for IoV based on post-quantum blockchain. Through our analysis and experiment, this new scheme can increase the efficiency of energy utilization and enrich EI’s application in IoV. In particular, we further illustrate and analyze its performance. It is shown that EI based on post-quantum blockchain is more secure and efficient in information communications and energy trading.
