Abstract
The Vehicle-to-Grid (V2G) paradigm facilitates bi-directional energy and data exchange between Electric Vehicles (EVs) and the Smart Grid, enhancing power distribution efficiency and dynamic grid interaction. However, this open communication framework presents authentication-related security risks, particularly impersonation, Man-in-the-Middle (MITM), and replay attacks. This paper offers a focused analysis of these vulnerabilities by reviewing typical attack models and evaluating how current authentication protocols respond to them. Special attention is given to lightweight, certificate-based mutual authentication mechanisms employing Transport Layer Security (TLS) and Public Key Infrastructure (PKI). Through step-wise examination, the paper assesses the strength and limitations of these strategies in practical V2G environments, highlighting deployment challenges and security considerations.
