IFA in Named Data Networking (NDN) : Case Study on INHERENT Topology

Named Data Networking (NDN) is part of an NSF research project that started in 2010 and was created to be implemented as a future Internet architecture. NDN as a network service has evolved from an Internet host-based packet delivery model to an Internet content-based packet delivery model. Attackers design various attacks for NDN networks by exploiting the interaction between interest packets and data packets. IFA is one type of DDoS attack on NDN networks. IFA attackers would overload intermediate routing nodes by requesting a large number of fake Interest packets. In this paper, the interest-flooding attack model is tested by varying the attack time and location of the attacker. The results show that IFA attacks are more effective when the consumer is closer to the producer due to the increased latency resulting from the attack.
