With Plug & Charge according to ISO 15118-2, security depends on the trusted management of digital identities, certificates, and cryptographic keys. If a certificate is stolen or an identity is compromised, an attacker can mimic legitimate communication without the problem being outwardly visible during normal charging. As V2G and V2H technologies evolve, so does the systemic risk. Coordinated manipulation of a large number of charging points can alter their output, create unwanted peaks, and threaten grid stability. nttdata.com 🇩🇪
