Post-Quantum Secure Lattice-Based Lightweight Authentication Scheme for Energy Internet-Based V2G Communication

This research presents a new authentication protocol (a method for verifying identity between two parties) designed for Vehicle-to-Grid (V2G) communication, which allows electric vehicles to securely exchange energy with charging stations. The protocol uses lattice-based cryptography (a type of math-based encryption resistant to attacks from quantum computers, which are extremely powerful future computers) and was tested for security using both automated tools and manual analysis to ensure it works safely in real-world situations.
