Cooperative Routers against DoS Attacks

Abstract

In order to protect network from the Denial of Service attacks which sends excessive traffic to a host, it is required for network components to throttle unauthorized traffics. The attacker must be identified through the cooperation of routers and must be isolated by the nearest router. It is the most important to identify and isolate the attacker since the nearest router can make ideal blocking of the DoS attacks. In this research, we will present a protocol which can identify the attacker of DoS by the request of victim in cooperation of routers on the attacking path between a victim and the attacker. The performance of our protocol will be verified by simulations and the experiments show that it takes considerably small time to identify the location of attacker.
