Security using reconfigurable intelligent surfaces and wind energy harvesting

Reconfigurable intelligent surfaces (RIS) have emerged as a promising technology for enhancing wireless communication performance by intelligently manipulating the propagation environment. When integrated with wind energy harvesting, RIS can operate sustainably, making them an attractive option for remote and environmentally conscious deployments. This paper investigates the physical layer security of RIS-assisted communication systems powered by wind energy harvesting. Specifically, we evaluate the secrecy outage probability (SOP) and the strictly positive secrecy capacity (SPSC) as key performance metrics to assess the system's resilience against eavesdropping attacks. By modelling the random nature of wind energy and incorporating its impact on the RIS operation, we derive analytical expressions for SOP and SPSC under various environmental and system configurations. Our results reveal the interplay between wind energy availability, RIS configurations, and physical layer security, providing valuable insights into designing secure and sustainable RIS-based communication systems.
