A Secure Authenticated Message Transfer in Vehicle to Grid Networks

Due to the recent emerging trends in technology, Vehicle to Grid (V2G) networks plays a major role in smart grid system. Now a days using of electric vehicles has increased than the usage of fuel-based automobiles under transportation. Electric vehicles mainly use electricity instead of fuels that is distributed by the charging terminal. Generally, the charging terminal will be situated in gasoline stations or on road sides and electric vehicles get charged at the stations. In V2G communication networks, the communication takes place between the charging terminal and the electric vehicle will be affected by several cyber-attacks. In addition to that, the electric vehicle owner’s personal information should be kept secure. In this proposed system, charging terminal and electric vehicles initially register their identities at the control authority. Using of Anonymous mutual authentication scheme, the charging terminal and the electric vehicle authenticates with each other and establish protected communication between them. During Session Key Exchange protocol, the information passed from the charging terminal will be transferred to the electric vehicle with the help of session keys. Duplicate identity of the charging terminal and electric vehicle is created in order to protect the original identity of the users who are present in V2G networks. Proposed scheme gives strength against various security attacks and cost of the system is also reduced. The main aim of this proposed system is to maintain confidentiality and integrity among the V2G communication networks.
