Abstract:

To meet the demand of high spectrum and energy efficiency in future wireless communication systems, intelligent reflecting surface (IRS), a promising technology has attracted significant attention.By proper design of IRS, PLS can be boosted from different perspectives.Based on that, current research about IRS-assisted PLS enhancement from various aspects, e.g., information-theoretic secrecy, covert communication, secret key generation and so on, were summarized.The system features and key solutions of the related papers were reviewed and several future research directions were discussed.

Key words: intelligent reflecting surface, wireless communication system, physical layer security
