Extensible Post Quantum Cryptography-Based Authentication

This research presents a new authentication protocol designed to work with quantum-safe cryptography (security methods that will remain secure even after powerful quantum computers are built). The protocol uses lattice-based algorithms (mathematical approaches based on complex grid structures) for digital signatures and key exchange, and is built to work in resource-limited environments while maintaining forward secrecy (ensuring that even if current keys are compromised, past communications remain protected).
