Authentication protocol built from a chaotic cryptosystem for a fog and cloud-based CWD-WPT charging station
Luis Fernando Arias Roman, Paulo Roberto de Lira Gondim · 2021
In vehicular ad-hoc networks for electric vehicles (EV), the possibility of charging EVs while driving (CWD) with the use of wireless power transfer (WPT) technology offers advantages such as optimization of travel time and greater comfort for travelers. On the other hand, the privacy, confidentiality and integrity of the users' information must be guaranteed for preventing security attacks (e.g., Man-in-the-Middle and Denial-of-service (DoS)). This article presents a new authentication protocol that uses a chaotic map-based cryptosystem for key generation, validation, and key distribution in a cloud-based CWD-WPT loading station. The composite protocol ensures mutual authentication between the recharge system and the EV, as well as privacy and anonymity of users with excellent performance in terms of communication and computational costs, and resistance to attacks.
