Research on WAPI-based Secure Access Technology for Power Internet of Things Terminals
In order to improve the secure access capability of power internet of things(IoT)terminals,enhance the channel capacity and operational stability of data gateways,a power IoT terminal secure access system based on wireless LAN authentication and privaly infrastructure(WAPI)was designed.The wireless LAN authentication and confidentiality infrastructure modules through encrypted wireless network technology was constructed to achieve secure transmission of power terminal data;a gateway state prediction model was built for power terminals connected to the IoT using IoT technology,the routing nodes of the terminal gateway using the shortest optimization method were divided,and an information channel transmission model was designed;the Lagrangian algorithm was used to improve the analysis scheme of transmission channel capacity into multi period prediction.The accurate prediction of the security access gateway status for power terminals was thus realized.Through experiments,it is shown that the data prediction accuracy of the system technology accounting is over 90%,achieving accurate prediction of the security access gateway status of power terminals and laying the foundation for other technical researches.
