Research on Security Isolation Method for Wireless Public Network Oriented to Smart Power Distribution Service

摘要

Intelligent distribution of communication networks is a key link to ensure power supply reliability, improve grid operation efficiency and service quality. Aiming at the security problem of wireless public network communication access with power terminal in the background of smart grid, by analyzing the current status of power wireless public network access, analyzing the security isolation requirements of the distribution terminal service, based on Bayesian classification algorithm will be used. The electrical service is securely partitioned, and a simple security isolation architecture for wireless public network access is proposed. The security zone and the wireless public network are isolated by the terminal server, and a specific security isolation scheme is elaborated. This method provides end-to-end and hierarchical high-quality services for the service, and has simple operation and low investment. It is of great significance for the future application of the wireless public network in the distribution of the electric communication network.
