A Cross-layer Security Analysis and Synthesis Method of B5G Base Station in Industrial Internet

With the increasing popularity of B5G base stations in the field of industrial internet, the perception and prediction of their security situation have become a current research hotspot. This paper studies the cross-layer analysis and synthesis problem of B5G base stations, and proposes a new Gl-anti-entropy nested weighting method to address the various issues of the existing “subjective-objective parallel weighting” method, such as complex steps and poor interpretability. Based on this, a cross-layer analysis model of B5G base stations is established according to the hierarchical structure of “system-unit-module” in B5G base stations to finally obtain the system-level security degree of B5G base stations. The research results show that the proposed cross-layer analysis and synthesis method of B5G base station in industrial Internet can effectively characterize the system-level security condition of B5G base stations.
