Abstract
Electric Vehicles (EVs) with numerous optimized features are becoming more popular in today’s world of vehicle technology. This is especially in these days when climate change is becoming more of a concern, and the usage of renewable energy is promoted. These EVs require frequent charging for daily use, and the usage of different charging stations would store sensitive data about EVs, e.g., location, driver’s license, etc. This leads to significant privacy and security concerns. In this paper, we will investigate the existing solutions proposed in the literature to address these concerns. Some of these solutions are implementing a framework that depends on cryptography and the Matching Market, where cryptography plays a vital role in securing user information privacy. Other solutions include implementing a secure and privacy-preserving physical layer-assisted scheme for charging stations to improve authentication and preserve user privacy. Finally, we provide a comprehensive comparison of the existing works, followed by our recommendations for future research directions to enhance the security level for future electric vehicle transportation systems.
