“…The physical layer authentication method based on compressed sensing channel information through multiple antenna arrays can meet the demand for lightweight authentication in time-varying wireless environments for future resource-constrained networks such as 5G networks, IoT, and sensor networks. The inherent drawback of physical layer authentication techniques is that initial authentication is not possible, so physical layer authentication needs to be combined with traditional authentication mechanisms and rely on traditional upper layer authentication techniques for the initialization of authentication [23]. In this paper, the combination of physical layer authentication methods based on compressed channel information of multiantenna array and upper-layer authentication can constitute a cross-layer authentication scheme, whose flowchart is shown in Figure 3.…”

Large-scale antenna technology has become one of the most promising technologies in 5G because of its ability to effectively improve the spectral efficiency and energy efficiency of the system, as well as its better robustness. In this paper, a large amount of CSI (channel state information) data is characterized by feature mining and law analysis, and a large number of channel characteristics of the physical layer have the advantages of randomness and uniqueness, etc. From the perspective of improving the security of the authentication mechanism and reducing the computational complexity of the authentication mechanism, the physical layer security authentication model is analyzed, and the signal security transmission path, signal authenticity, and channel estimation are used to propose an effective physical layer secure transmission and authentication mechanism, which can be used as a security enhancement and lightweight authentication mechanism for existing authentication mechanisms. In this paper, we analyze the security advantage mechanism of physical layer authentication and prove the security performance boundary; propose an authentication security enhancement method based on the channel feature generation key, a message authentication method based on superimposed tag signals; and propose a method based on private guide frequency for high-speed service data authentication.
