Abstract: The present invention relates to a rough set driven quantum-safe authentication and session key establishment framework for Edge-IoT devices. The proposed framework provides a secure, lightweight and adaptive mechanism for authenticating resource-constrained edge nodes and establishing protected session keys in post- quantum computing environments. The method integrates rough set theory for uncertainty handling, attribute reduction and decision-rule generation during device authentication. Device parameters such as identity attributes, trust score, communication behaviour, resource status, access history and network context are analyzed using rough set-based approximation to classify legitimate, suspicious and unauthorized devices. After successful authentication, a quantum-safe key establishment process is executed using post-quantum cryptographic primitives to generate a secure session key between the Edge-IoT device and the gateway or edge server. The framework further supports nonce exchange, timestamp verification and context-aware validation to prevent replay, impersonation, man-in-the-middle and key compromise attacks. The rough set module reduces unnecessary authentication attributes, thereby lowering computational overhead, memory usage and communication latency. The invention is suitable for smart healthcare, industrial IoT, smart grids, vehicular edge networks and other distributed IoT environments where secure and efficient communication is required against both classical and quantum-enabled attacks.
