5G网络共建共享安全研究

Research on Security of 5G Network Co-Construction and Sharing

随着5G网络建设和运营成本的不断增加,5G网络共建共享的必要性和战略意义凸显。目前国内共建共享采用5G MOCN网络架构,使得共建共享双方的移动网络由封闭转向开放,带来了开放性的安全风险。从5G共建共享网络架构出发,分析接入网、承载网、核心网、网管系统等由于共建共享带来的新的安全风险及相应的应对策略,从而保障共建共享场景下双方的网络安全。

With the increasing costs of 5G network construction and operation,the necessity and strategic significance of 5G network co-construction and sharing have gradually become prominent.At present,5G MOCN architecture is adopted in domestic,which makes the mobile network of both parties transform from closed to open,and brings open security risks.It starts from the architecture of 5G co-construction and sharing network,sorts out the new security risks brought by the co-construction and sharing,analyzes corresponding strategy for the access network,bearer network,5G core network,and network management system,so as to guarantee the security of both sides network under the co-construction and sharing scenario.
