In the future, 5G networks will not only be used for communication between people, but also for communication between people and things and between things. At present, 5G services can be roughly divided into three scenarios: eMBB (enhanced mobile broadband), mMTC (massive machine-type communication), and uRLLC (ultra-reliable and low-latency communication). 5G networks require different security measures for these three business scenarios. Differentiated security protection mechanisms are required. Fiber optic ribbon splitter

eMBB focuses on services that have extremely high demand for bandwidth, such as high-definition video, VR (Virtual Reality) / AR (Augmented Reality), etc., to meet people’s needs for digital life. The wide range of application scenarios of eMBB will bring different security requirements. Different services in the same application scenario have different security requirements. For example, personal services such as VR/AR may only require encryption of key information transmission, while for industry Applications may require that all environmental information be transmitted encrypted. 5G networks can meet the security requirements required by eMBB scenarios by extending LTE security mechanisms.

mMTC covers scenarios with high connection density requirements, such as smart cities, smart agriculture, etc., which can meet people’s needs for a digital society. Facing the complex application types and hundreds of billions of connections in the Internet of Things, 5G networks need to consider the diversity of their security requirements. For IoT devices with low computing power and high battery life requirements, 5G networks should ensure energy efficiency through some security protection measures (such as lightweight security algorithms, simple and efficient security protocols, etc.).

uRLLC focuses on services that are extremely sensitive to latency, such as autonomous driving/assisted driving, remote control, etc., to meet people’s needs for digital industries. Low latency and high reliability are the basic requirements of uRLLC services. The realization of 5G ultra-low latency requires a series of mechanism optimizations in each link of end-to-end transmission. From a security point of view, to reduce the delay, it is necessary to optimize the identity authentication delay in the service access process, the delay caused by the security protection of data transmission, the delay caused by the security context switching during the terminal movement process, and the data storage in the network node. The delay caused by encryption and decryption processing. Fiber optic ribbon splitter

Therefore, in the face of various application scenarios and business requirements, 5G networks need a unified, flexible and scalable 5G network security architecture to meet the security requirements of different security levels of different applications, that is, 5G networks need a unified authentication framework , to support network access authentication in various application scenarios (that is, to support the authentication of terminal equipment, to support the authentication of subscribers, to support the authentication of multiple access methods, to support multiple authentication mechanisms, etc.); at the same time, the 5G network should support
Scalability requirements, such as the need to start security function instances in time to meet the increased security requirements when the network is horizontally expanded, and to terminate some security function instances in time when the network converges to achieve the purpose of energy saving.
