Threat of DoS by interest flooding attack in content-centric networking

Content-Centric Networking (CCN) is one of promising architecture based on ICN concept for Future Internet. In contrast to current IP network, CCN can overcome inefficient content distribution caused by the IP architecture in the situation of today´s traffic flooding of internet. However, CCN is exposed to Denial of Service (DoS) attack by sending large number of Interest rapidly, called Interest flooding attack since content name in Interest cannot be verified in CCN. In this paper, we prove that Interest flooding attack can be applied for DoS in CCN based on the simulation results which can affect quality of service. We expect that it contributes to give a security issue about potential threats of DoS in CCN.
