After the launch and popularization of 5G networks, higher requirements for network security are bound to be put forward, and network security insurance is one of the effective ways to deal with this problem. The blessing of artificial intelligence technology text message service and the full spread of 5G construction have accelerated the popularization of the industrial Internet, including cloud computing, mobile Internet, Internet of Things/Internet of Vehicles, big data, blockchain, cloud storage, artificial intelligence/face recognition/ The wide application of new technologies such as autonomous driving has rapidly brought about new changes in the Internet world and has become a key driving force for enterprise growth and transformation. According to IDC statistics, the global digital information will show astonishing growth in the next few years, and the total amount is expected to increase by 44 times by 2020. Another survey showed that 90% of the world's data was generated in the past two years. Every day, sensors, mobile devices, online transactions and social networks in every corner of the world generate terabytes of data. There are currently 30 billion text message service connected devices, and 50 billion devices will be connected by 2020. While new technologies bring changes, new risks also come with them. When the insurance industry introduces new technologies such as artificial intelligence for underwriting and claim settlement, it must take into account the risks caused by possible errors and how to deal with them. 5G network puts forward higher requirements for security At present, 5G is opening up a new era of mobile communication development and accelerating the digital transformation of the economy and society.

The 5G network puts forward higher requirements for security. The application scenarios of the Internet of Everything, diversified terminal forms and access technologies, mobile edge computing technology, and network slicing technology will generate new security issues. Pseudo base station protection, network security, integrity, and authentication types are used to improve network security in the context of 5G.
