Overview of Security Technologies and Strategies for Intelligent Railway 5G
Digital technology is reshaping all walks of life,which is the only way for the development of the industry.While digital servitization technologies such as 5G empower industries such as railways,they also bring some security risks.Security is a pre-requisite for all services.In order to promote the innovative applications of 5G in intelligent railway,this paper first systematically reviews the security risks and challenges faced by intelligent railway 5G from the perspectives of terminal,air interface,communi-cation,data,system,and public-private network integration.In view of new service scenarios,we analyze the new technologies,new terminals and new applications for railways,and the new requirements of 5G security for smart railways.The new features of 5G security enhancement in aspects of password algorithm,air interface security,privacy,unified authentication,and roaming are also summarized.On this basis,the key points of smart railway 5G security are given,including certification,physical layer securi-ty,terminal security,slice security and edge computing security.For 5G private network deployment,recommendations are also given in terms of infrastructure,communication security,data security,and endogenous security defense system.
