Abstract: In order to accurately judge the abnormal behavior of network traffic, ensure the security of power communication data storage and improve the effect of wireless monitoring of environmental security of power communication engineering, the wireless monitoring method of environmental security of power communication engineering based on RSA algorithm is studied. Design the technical framework of wireless monitoring method for environmental safety of power communication engineering, collect the environmental network data of power communication engineering by using the control network and transmit it to the management network; RSA algorithm is used to encrypt and process the network data received by the management network, and the encrypted network data is stored in the database; Using time series graph mining method to analyze the encrypted network data and judge the abnormal behavior of network traffic; Analyze the correlation characteristics between network traffic with abnormal behavior, calculate the average correlation coefficient of abnormal network traffic, detect the type of network attack, and realize the wireless monitoring of environmental security in power communication engineering. The experimental results show that this method can effectively encrypt the network data of power communication engineering environment and improve the security of network data storage; This method can accurately judge the abnormal behavior of network traffic, accurately detect the type of network attack, and realize the wireless monitoring of environmental security of power communication engineering.
