5G安全技术与标准

Overview and prospect of 5G security

移动通信从4G演进到5G的过程中,在网络演进和业务需求的促进下,安全设计的理念进一步完善,安全能力更加丰富。指出5G网络安全的设计理念是在开放的环境下构建安全的网络与服务,基于对3GPP、ITU、GSM中的5G安全标准的综合分析,梳理出网络自身安全保障、垂直行业支撑、安全测评认证3条主线。基于这3条主线,对5G网络中引入的安全新技术、安全新能力、安全新风险进行深入分析,并对5G安全未来发展趋势和重点工作提出建议。

From 4G to 5G,as the result of network evolution and service promotion,the concepts and principles of security in design were deeply integrated,the security capabilities were enhanced.The root of 5G security design-building secure networks and services in the open environment were analyzed.Furthermore,according to the understanding of the 5G security specifications designed by 3GPP,ITU and GSMA,the security framework and these new technologies were analyzed in detail from three aspects:network security assurance,service security capabilities and security assessment methodologies.The overview of 5G security trends and the key works in the long run were summarized.
