Abstract: The anomaly triggered by intentional attack in complex networks is common but most existing detection methods ignore the global topology mutation feature. To solve this problem, based on the abnormal evolution characteristics of the global network topology, a network path change coefficient (r) was proposed to quantify the change of the transmission path between nodes. The Fibonacci evolution region was derived from the Fibonacci sequence to distinguish normal and abnormal evolution. r was used as the core measurement parameter to construct the Fibonacci evolution region, form a network anomaly detection method, and realize the determination of anomalies. The results showed that the average accuracy of the detection method is more than 90%, which is higher than the accuracies of MCS (maximum common subgraph) and GED (graph edit distance), which proves the effectiveness of the proposed detection method.
