Survey on Physical Layer Security Research for IRS-assisted UAV Communication Systems
摘要
Abstract
In recent years,UAV has played an important role in modern communication networks due to their high flexibility and diverse application scenarios.However,since UAV communication links typically operate in open airspace,they are highly vulnerable to eavesdropping and malicious interference,making Physical Layer Security(PLS)an urgent issue to be addressed.As a novel two-dimensional artificial electromagnetic surface,the Intelligent Reflecting Surface(IRS)consists of numerous passive scattering units with specially designed structures,which can intelligently adjust signal reflection paths.This provides a new technological approach to improving channel conditions and enhancing physical layer security.Consequently,the application of IRS in UAV communications has attracted widespread attention and offers a new direction for addressing communication security issues in open airspace.Through a review of existing domestic and international literature,the research status of ground-fixed IRS systems and UAV-mounted IRS systems in PLS are summarized,focusing on three aspects:Secrecy Rate(SR),Secrecy Energy Efficiency(SEE),and Secrecy Outage Probability(SOP).The existing shortcomings in current research are analyzed and an outlook on future research directions for IRS-assisted UAV communication systems in the field of PLS are provided.关键词
