Current Trends in Digital Twin and IoT Security

The research landscape in digital twins and IoT security is witnessing significant advancements, particularly in formal verification and dynamic software updating. Digital twin technology is increasingly being formalized through methodologies that translate uncertain processes into finite state machines, ensuring controlled information leakage while maintaining theoretical guarantees. This approach is pivotal for complex systems, such as unmanned aerial vehicles, where synchronization between physical and virtual data flows is critical. The integration of digital twins across various industrial sectors, from healthcare to manufacturing, is also advancing, with a focus on real-time data communication and addressing privacy and security concerns.

In the realm of IoT security, dynamic software updating (DSU) techniques are evolving to enhance energy efficiency, operational durability, and security in IoT environments. The survey highlights the importance of balancing operational efficiency, security, and adaptability in DSU strategies, which are essential for the resilience and sustainability of IoT devices. Additionally, the security of wireless sensing technology is being systematically reviewed from a role-based perspective, categorizing research into victim, weapon, and shield roles of wireless signals. This classification method is crucial for understanding and addressing the multifaceted security challenges in wireless sensing applications.
