A Fuzzy Anomaly Detection Model Based on Genetic Algorithm with Hash Function for IPv6

In order to accomplish the anomaly detection based on IPv6,we developed a novel anomaly detection model using a fuzzy anomaly detection rules generation technology for IPv6 with genetic algorithm.In the model,we optimize the initial population using Hash algorithm,encode the population using random real values,and detect the anomaly using fuzzy detection rules.Finally,using the CERNET2 backbone traffic,this paper analyzes the performance of the model and compares with the performance of snort.This study shows that the anomaly detection model provided in this paper has two advantages: algorithm performance and detection effect.
