Towards Cyber Security for Low-Carbon Transportation: Overview, Challenges and Future Directions

In recent years, low-carbon transportation has become an indispensable part as sustainable development strategies of various countries, and plays a very important responsibility in promoting low-carbon cities. However, the security of low-carbon transportation has been threatened from various ways. For example, denial of service attacks pose a great threat to the electric vehicles and vehicle-to-grid networks. To minimize these threats, several methods have been proposed to defense against them. Yet, these methods are only for certain types of scenarios or attacks. Therefore, this review addresses security aspect from holistic view, provides the overview, challenges and future directions of cyber security technologies in low-carbon transportation. Firstly, based on the concept and importance of low-carbon transportation, this review positions the low-carbon transportation services. Then, with the perspective of network architecture and communication mode, this review classifies its typical attack risks. The corresponding defense technologies and relevant security suggestions are further reviewed from perspective of data security, network management security and network application security. Finally, in view of the long term development of low-carbon transportation, future research directions have been concerned.Comment: 34 pages, 6 figures, accepted by journal Renewable and Sustainable Energy Review

Authentication and Billing Scheme for The Electric Vehicles: EVABS

The need for different energy sources has increased due to the decrease in the amount and the harm caused to the environment by its usage. Today, fossil fuels used as an energy source in land, sea or air vehicles are rapidly being replaced by different energy sources. The number and types of vehicles using energy sources other than fossil fuels are also increasing. Electricity stands out among the energy sources used. The possibility of generating electricity that is renewable, compatible with nature and at a lower cost provides a great advantage. For all these reasons, the use of electric vehicles is increasing day by day. Various solutions continue to be developed for the charging systems and post-charge billing processes of these vehicles. As a result of these solutions, the standards have not yet been fully formed. In this study, an authentication and billing scheme is proposed for charging and post-charging billing processes of electric land vehicles keeping security and privacy in the foreground. This scheme is named EVABS, which derives from the phrase "Electric Vehicle Authentication and Billing Scheme". An authentication and billing scheme is proposed where data communication is encrypted, payment transactions are handled securely and parties can authenticate over wired or wireless. The security of the proposed scheme has been examined theoretically and it has been determined that it is secure against known attacks
