摘　　要：As the 6th-Generation(6G)wireless communication networks evolve,privacy concerns are expected due to the transmission of vast amounts of security-sensitive private information.In this context,a Reconfigurable Intelligent Surface(RIS)emerges as a promising technology capable of enhancing transmission efficiency and strengthening information security.This study demonstrates how RISs can play a crucial role in making 6G networks more secure against eavesdropping attacks.We discuss the fundamentals and standardization aspects of RISs,along with an in-depth analysis of Physical-Layer Security(PLS).Our discussion centers on PLS design using RIS,highlighting aspects including beamforming,resource allocation,artificial noise,and cooperative communications.We also identify the research issues,propose potential solutions,and explore future perspectives.Finally,numerical results are provided to support our discussions and demonstrate the enhanced security enabled by RIS.
