Research on Network Security Protection Technology of Power Dispatching Automation
For the security protection of power dispatching data information in China,this research sets up a capacitance detec-tion module at the physical level of the equipment to prevent external devices from accessing the power information collection e-quipment to steal information.In addition,at the data information level,the encrypted database is encrypted by the double-lay-er stop and wait protocol(SWP)encryption structure(symmetric encryption algorithm),and the data information transmission node is encrypted to protect the main control center database and data information transmission node from being attacked by malicious programs and prevent the transmitted information from being attacked by malicious programs.intercept.Experiments show that the system designed can maintain a stability of more than 80%under information attacks,and can identify sudden changes in device capacitance of 1 μF.
