Research on gray correlation analysis and situation prediction of network information security

Abstract

In order to further improve the accuracy and efficiency of network information security situation prediction, this study used the dynamic equal-dimensional method based on gray correlation analysis to improve the GM (1, N) model and carried out an experiment on the designed network security situation prediction (NSSP) model in a simulated network environment. It was found that the predicted result of the improved GM (1, N) model was closer to the actual value. Taking the 11th hour as an example, the predicted value of the improved GM (1, N) model was 28.1524, which was only 0.8983 larger than the actual value; compared with neural network and Markov models, the error of the improved GM (1, N) model was smaller: the average error was only 2.3811, which was 67.88% and 70.31% smaller than the other two models. The improved GM (1, N) model had a time complexity that was 49.99% and 39.53% lower than neural network and Markov models; thus, it had high computational efficiency. The experimental results verify the effectiveness of the improved GM (1, N) model in solving the NSSP problem. The improved GM (1, N) model can be further promoted and applied in practice and deployed in the network of schools and enterprises to achieve network information security.

An Intelligent Grey Correlation Model for Online English Teaching Quality Analysis

“…where δ 2 (X, X) describes the high level of clustering closeness; α/D(X, R) describes the correlation between the state of the cluster distribution and the geometric orientation of the cluster centers, which is used to balance the interference of the 2 evaluation metrics on the clustering criterion [21][22][23][24].…”

Computer Network Information Security and Protection Strategy Based on Big Data Environment

“…As the world is undergoing major changes and facing new crises and challenges in network technology and information security, the global community must strengthen solidarity and cooperation in the network world and safeguard fairness and justice to share data dividends (Ping, 2022;Ye, Shi, & Zhang, 2021). In securing security, the security technology platform should focus on consolidation to improve security protection.…”

“…BC itself facilitates the penetration of supervision and the operation of asset securitization directly through the end of the asset. Then, it can realize the separation of main credit rating and project rating, invest funds in target assets, and solve related issues such as own development funds (Ye et al;Zhang et al, 2020;Zhang et al, 2021b;Zhang et al, 2022;Djuitaningsih & Arifiyantoro, 2020).…”
