Analysis of physical-layer security in future mobile communication

The security threats in LTE (long time evolution) and the existing security mechanisms in mobile communication system are briefly introduced. In view of the development of the physical-layer security and the research of the security mechanisms in physical-layer, we analyze the application and advantages of the physical-layer security in future mobile communication system. A new authentication process is put forward based on the physical-layer security techniques, which can simplify the signaling interaction as well as enhance the security of the system.
