Abstract
Even though the electric vehicles (EVs) are getting greater attention in recent years, still a lot of advancement in EV technologies is required to support widespread adoption of EVs. A lot of attention is focused on the authentication and authorization mechanisms for the EV charging infrastructure. Existing EV charging networks extensively use RFID smart cards for authentication and authorization purposes. Furthermore, ISO/IEC (International Organization for Standardization/International Electrotechnical Commission) 15118 standard has defined certificate based authentication and authorization mechanism for EV charging. However, since these techniques are unimodal and single path, they have low security and can be vulnerable to various malicious attacks. Multimodal and Multi-pass Authentication mechanisms have been proposed for EV networks. Deploying such mechanisms, various attacks such as man-in-the-middle attacks, substitution attacks can be mitigated.
