Survey on research and standardization of 5G security technology

With the commercialization of fifth generation wireless systems (5G) and their development in vertical fields such as Internet Things, security issues are increasingly gaining attention. This paper provides latest survey on 5G network pertaining to potential threats, architecture, technology. The begins with vulnerabilities 5G, which can be classified according system availability, information integrity, authentication, privacy, confidentiality protection. Then, threats attack methods encountered at different levels analyzed. Subsequently, architecture relevant standards is briefly described. Based technologies reviewed based three categories beyond (B5G), physical, network, application layers. Finally, concludes by presenting observations future directions B5G security.
