Abstract:
Traditional fuel based automobiles are being replaced swiftly with other source oriented vehicles such as solar and electric powered etc. Electric automobiles (EAMs) are one of the emerging and accessible technologies in the transportation sector to decrease CO2 eruptions and oil demand making up the basis of vehicle to grid (V2G) networks. The V2G systems provide electric energy to Electric automobiles (EAMs) to charge their batteries through aggregating charge stations (ACSs) upon which EAMs are able to function and run. While EAMs are fast replacing conventional Internal Combustion Engines (ICEs), there are emerging threats in terms of security and efficiency in this domain. Since the sensors and devices in V2G frameworks are often resource constraint as no complex hardware is deployed. Mutual authentication among different entities involved in V2G systems, confidentiality and privacy preservation of personal data remains a challenging task. This research proposes a novel user key exchange authentication scheme (NUKA) for V2G based frameworks addressing above mentioned challenges. Informal and formal analysis of NUKA in terms of efficiency and security shows that the proposed scheme is lightweight with enhanced performance and maximum security features as compared to existing schemes.
