With the increase of internal data interaction activities in the digital hydropower centralized control center,the security risk of interactive data is increased.In order to improve the security of data interaction,the design of data security interaction in digital hydropower centralized control center based on trusted technology is proposed.Build the data interaction model of hydropower centralized control center,calculate the average attack probability of data interaction,and formulate the selection rules of data interaction nodes.Trusted technology is applied to generate trusted passwords for interactive data,protect the confidentiality of interactive data,and determine the behavior of data interaction nodes.From the perspective of behavior subject,object and environment,the credibility of node behavior is measured,and the data security interaction architecture is designed based on PCIE protocol to realize the security interaction of data in hydropower centralized control center.The experimental data shows that the maximum integrity of interactive data obtained by using the proposed method is 96%,and the maximum confidentiality of interactive data reaches 0.92,which proves that the proposed method has better data interaction security.
