摘　　要：5G时代的网络安全风险主要来源于其更广的连接范围、更高速的数据传输能力和更多样的应用场景,这些特性为网络攻击提供了新的入口和更大的攻击面,增加了数据泄露、设备劫持、服务拒绝攻击等风险的可能性,同时,由于5G网络支持海量物联网设备接入,设备的安全漏洞攻击及供应链风险也对网络稳定性构成巨大威胁。本文针对基于SDN的5G网络安全架构开展了简要分析,探讨了应用层、控制层、数据传输层的功能及具体部署形式。同时分析了网络安全架构下的数据加密认证技术。期望以本文,可为相关企业提供借鉴和思考价值,从而进一步优化我国5G网络安全水平,为数据安全传输与用户个人信息安全提供坚实的基础。The network security risks in the 5G era mainly come from its wider connection range,higher data transmission capacity and more diverse application scenarios.These characteristics provide a new entrance and a larger attack surface for network attacks,and increase the possibility of risks such as data leakage,device hijacking and denial of service attacks.At the same time,because the 5G network supports the access of massive Internet of Things devices,the security vulnerability attacks of devices and supply chain risks also pose a great threat to network stability.This paper briefly analyzes the security architecture of 5G network based on SDN,and discusses the functions and specific deployment forms of application layer,control layer and data transmission layer.At the same time,the data encryption and authentication technology under the network security architecture is analyzed.It is expected that this paper can provide reference and thinking value for related enterprises,so as to further optimize the security level of China's 5G network and provide a solid foundation for data security transmission and user personal information security.
