Abstract

Vehicle-to-grid (V2G) refers to the bidirectional communication and energy flows that allow renewable energy sources to supply supplementary electrical services between electric cars (EVs) and the power grid. Additionally, V2G lowers environmental pollution and energy issues while providing efficient charging services. A PUF-based, reliable, anonymous authentication and key establishment scheme for V2G networks was recently presented by Sungjin Yu et al. In this paper, we show that the Yu et al. protocol is vulnerable to tracking attacks and does not guarantee user anonymity. We also discovered that ephemeral secret leakage attacks can target their scheme. Additionally, we propose a new PUF-based authenticated key establishment scheme for V2G networks that is more effective than the most recent relevant scheme and is resistant to all known attacks. We prove that the presented scheme is semantically secure, and we also simulate our protocol using the Scyther tool.
