Abstract: Physical layer security technology secures wireless communications based on information security theory, which is the key means to realize the integration of security and communication, and has become gradually a research hotspot at home and abroad. The research of key generation technology in the physical layer of wireless communication is studied, mainly focusing on the theoretical model, mechanism and research status of key generation technologies. Through the comparison and analysis of the two different types of key generation algorithms, that is, the source key generation algorithm and the channel key generation algorithm, the essence of physical layer key technologies using communication channel’s inherent security attributes to promote communication security is revealed. In particular, a feasible physical layer key generation 5G engineering implementation framework is presented. Finally, the possible future research directions of physical layer key generation technologies is prospected.
