Abstract
Greener and more energy-efficient transportation options have pushed electric vehicles to the forefront of the global transportation market. Since then, academia and the transportation industry have tried to develop sustainable protocols that ensure dependable, scalable, and secure communication. With this vision, various security researchers have suggested authentication techniques to protect the messages exchanged between entities of the charging system. In its continuation, Kim et al. have proposed a charging system for electric vehicles based on the blockchain. With a close analysis of this protocol, our team has found that their scheme suffers from message substitution attacks, session key disclosure attacks, man-in-the-middle attacks, etc. This article proposes a secure and robust blockchain-based electric vehicle charging system using the ECC cryptosystem and lightweight one-way hash functions. Furthermore, the security of the proposed protocol is being analyzed, and the results confirm that the suggested protocol can withstand significant attacks.
