Abstract

ISO 15118 enables charging and billing of Electric Vehicles (EVs) without user interaction by using locally installed cryptographic credentials that must be secure over the long lifetime of vehicles. In the dawn of quantum computers, Post-Quantum Cryptography (PQC) needs to be integrated into the EV charging infrastructure. In this paper, we propose QuantumCharge, a PQC extension for ISO 15118, which includes concepts for migration, crypto-agility, verifiable security, and the use of PQC-enabled hardware security modules. Our prototypical implementation and the practical evaluation demonstrate the feasibility, and our formal analysis shows the security of QuantumCharge, which thus paves the way for secure EV charging infrastructures of the future.
