V2G(vehicle-to-grid) is an integral part of the smart grid. To deploy a V2G network on a large scale, it is necessary to solve network security and trustworthiness and privacy protection of electric vehicle users (EV). Therefore, this paper proposes a privacy protection strategy for V2G networks based on consortium blockchain and attribute-based signature and designs an overall implementation scheme including system initialization, EV registration, anonymous authentication, optimized scheduling, local services, block construction and consensus mechanism. The strategy also uses the K-anonymity to protect the privacy of the EV’s geographic location, making it well compatible with charging and discharging services. Finally, security and performance analysis proved the feasibility of design scheme.
