| Abstract |
With the development of global urbanization, the requirements of traditional urban management are increasingly prominent. With the development of 5G technology, the delay of information transmission has been shortened, the speed of information transmission has been accelerated, and the large-scale wireless communication technology has become more mature. So, it has a profound impact on the construction of the smart city. But the technologies involved in the smart city still need to be solved, like the user data eavesdropping and tampering of the air interface, the DDOS (Distributed denial of service attack) attack of air interface from UE (user equipment), the malicious interference of the fake base station to air interface. This paper studies these security problems in detail and points out some solutions. These solutions include network slicing technology based on SDN (Software Defined Network) and NFV (Network Function Virtualization) technology. For these technologies, this paper also prospects some different future research directions. Finally, this paper is helpful to the research of 5G network security problems and puts forward some suggestions for future smart city construction. © 2021 SPIE. |
