Endogenous security in the physical layer of wireless communications:key technologies,advantages and future challenges
The rapid development of wireless communications has put forward higher requirements for the design of se-curity architectures for future communications.The broadcast and openness of wireless systems make information trans-mission vulnerable to security threats such as interception,eavesdropping and interference.Wireless endogenous security utilizes the intrinsic characteristics of the wireless channel and communication-related technologies to complement exist-ing security mechanisms and improve transmission security.According to the development trend of wireless security,the key technologies of endogenous security in the physical layer of wireless communication were discussed.Research over-views of wireless key generation technology,wireless authentication technology,and wireless encrypted transmission technology were given.The wireless communication physical layer endogenous security advantages,i.e.,uniqueness,compatibility,heterogeneity,and reproducibility,were analyzed.Explore how to realize the de-redundancy of the physi-cal layer architecture and the reuse of physical layer functions.Future work on key technologies for endogenous security in the physical layer of wireless communications is outlined.
