Abstract

In order to effectively detect interest flooding attack (IFA) in Named Data Networking (NDN), this paper proposes a detection method of interest flooding attack based on chi-square test and similarity test. Firstly, it determines the detection window size based on the distribution of information name prefixes (that is information entropy) in the current network traffic. The attackers may append arbitrary random suffix to a certain prefix in the network traffic, and then send a large number of interest packets that cannot get the response. Targeted at this problem, the sensitivity of chi-square test is used to detect the change of prefix of interest packets. Interest packets initiated by IFA attackers are usually attached to a real prefix, but with a randomly generated suffix attached. Taking into account of this problem, the similarity of interest packet prefixes is further detected. Finally, the detection results of the two aspects are combined to determine whether interest flooding attack has occurred or not. In addition, according to the symmetric routing characteristic of Pending Interest Table (PIT), we also send the forged interest packet back to the attacker, and then restrict the corresponding port of the attacker, so as to effectively suppress the IFA attack. The experimental results show that the method we proposed can not only detect IFA in NDN at the beginning of the attack, but also is more accurate and effective than other methods.
