Vehicle to grid(V2G)technology enables bidirectional energy flow between electric vehicles and the grid.One of the main bottlenecks in the successful implementation of V2G technology is the secure communication between electric vehicle users and service operators.Malicious attackers can obtain economic benefits and disrupt the billing process by forging the information of legitimate electric vehicle users.Therefore,it is necessary to achieve rapid authentication between electric vehicle users and service operators.However,there is significant isolation between different charging service operators,forming multiple trust domains.To solve the above problems,this paper proposes a cross domain authentication scheme for electric vehicles based on consortium blockchain and edge computing in V2G,which uses consortium blockchain technology to link trust domains of different operators to ensure that users can achieve rapid identity authentication between different operators.And it has been theoretically proven that this scheme has confidentiality,unforgeability,and user privacy.
