5G网络切片安全防护设计

Design of Secure Protection for 5G Network Slice

在5G时代,移动通信网络不仅仅服务于个人消费者,更重要的是将服务于垂直行业,衍生出丰富的差异性业务。各种垂直行业的业务与应用类型各不相同,他们所面临的安全风险和威胁各不相同,同时各垂直行业对安全本身的诉求也各不相同。5G网络通过在统一的网络基础设施之上构建多个虚拟化逻辑网络切片的方式来满足这些垂直行业的差异化需求。因此,需要研究面向不同垂直行业用户和不同应用需要的网络切片安全问题,对行业用户和应用按需提供灵活、可定制性的多等级差异性安全防护能力,保障信息的合法使用。

In the 5G era, mobile communication networks would not only serve individual consumers, but more importantly, also serve vertical industries, resulting in a wealth of differentiated services. The vertical industries have different types of business and applications, and they face different security risks and threats. At the same time, vertical industries have different demands for security itself. 5G networks satisfy the differentiated demands of these vertical industries by building multiple virtualized logical network slices on top of a unified network infrastructure. Therefore, it is necessary to study the network slice security problem for different vertical industrial users and different application demands, and provide flexible and customizable multi-level differential security protection capability for industry users and applications, thus to ensure the legal use of information.
