[0002] In remote areas with harsh environments, the construction period of power communication networks is long and the cost is high. Therefore, by applying wireless communication technology, relevant IoT monitoring equipment can be connected to the wireless public network. Not only does it not need to repeat network construction and communication network upgrades, it is convenient to use and easy to expand. It also helps to complete power grid protection work and effectively implement power grid control. However, due to the single access security authentication method of the 5G public network, data security is difficult to guarantee.

[0003] In order to solve the above technical problems, the invention patent CN202310724584.6 "A communication security authentication method for power 5G network slices" uses public key infrastructure (PKI) or other encryption algorithms and access control to ensure that only authorized devices and users can access network slices, thereby realizing encryption processing of network data. However, there are the following technical problems: Since the network status of the 5G public network is unknown, and different encryption processing methods have different encryption and decryption processing complexities, if the encryption and security authentication processing methods of power Internet of Things devices in different regions cannot be determined according to the fluctuations in the network status of the 5G public network, it is possible that the fault data of the power equipment may not be known in the first time. In severe cases, it may even cause the failure range of the power equipment to expand, causing greater economic losses.

[0004] In view of the above technical problems, the present invention provides a method and system for power business security authentication considering wireless access. Summary of the invention
