Quantum-Resilient Self-Healing Cybersecurity Architecture for IoT-Enabled Smart Grids Using Federated Intelligence and Digital Twins

In this paper, the authors present a novel quantum-resilient self-healing cybersecurity system for smart grids with IoT technology, combining post-quantum security, federated intelligence, and digital twin technologies. The proposed framework facilitates distributed and private threat detection and ongoing monitoring of the grid’s behavior to detect any anomalous activities. Self-healing dynamically isolates adversely affected components and re-establishes secure operations with minimal service disruption. The architecture offers a scalable and adaptive security solution that helps establish the resilience of the smart grid to traditional and new quantum-related cyber attacks.
