5G network element distributed denial of service vulnerability detection method based on complex network

The invention relates to the technical field of communication, and particularly discloses a 5G network element distributed denial of service (DDos) vulnerability detection method based on a complex network, which comprises the following steps: step 1, firstly, respectively capturing pcap data packets of a 5G mobile communication network in a normal and distributed denial of service (DDos) attack scene, and realizing digital representation of interaction events on each path; step 2, establishing a representation data set according to a data interaction mode in the captured scene; step 3, automatically weighting the evaluation index through a genetic algorithm to obtain each node score represented in the topological structure; 4, constructing a complex network directed graph corresponding to the representation data set; 5, high-score nodes are obtained through node score descending order arrangement and sorting; and step 6, taking the interaction module in the overlapped part as a vulnerability detection result
