通信感知一体化物理层安全研究进展
Research Progress on Physical Layer Security of Integrated Sensing and Communication
摘要
Abstract
Facing the vision of the 6th Generation Mobile Communication Technology(6G)of the intelligent connection of all things,a new paradigm of communication and perception integration has been introduced,and the Integrated Sensing and Commu-nication(ISAC)technology has emerged.Due to the characteristics of highly integrated communication and perception data,the ISAC system is subject to severe interference and threats at the physical layer.This paper first outlines the basic principles and physical layer threats of the ISAC system.The discussion then turns to the technical principles and recent progress of key physical-layer security techniques for ISAC.This includes an in-depth look at artificial noise and precoding in the digital domain,as well as beamforming and intelligent reflecting surfaces in the spatial domain,concluding with a summary of the core emphases of each method.The physical layer of the ISAC system can combine multiple security technologies to build a highly secure physical layer environment from multiple dimensions,such as noise distribution and signal enhancement in the digital domain,and directional transmission and channel regulation in the spatial domain.Finally,the future development trends and challenges of the physical layer security of the ISAC system are prospected.关键词
