This study analyzes the performance of Secrecy Key Generation (SKG) in indoor scenarios supported by Reconfigurable Intelligent Surfaces (RIS), evaluating the impact of intelligent surface configurations on the security of Wi-Fi communications in the presence of shoulder-surfing attacks. The study explores the trade-off between increasing transmission performance and maintaining the entropy and cryptographic robustness of keys generated using Physical Layer Security techniques.
