Abstract：The typical security requirements for the main 5G application scenarios and new security challenges which are brought by the new 5G architecture are systematically analyzed. The security protection countermeasures are proposed, including trust operation of virtualization infrastructure and resource isolation, service-oriented and on-demand reconstruction of security network functions, network slicing security, unified identity management and multi-trust mechanisms, service based interface security, and security protection of network function domains, etc. These countermeasures provide network security research and design reference for 5G network to better adapt to the security needs of vertical industry differentiation.
