A Novel Protocol for IP Traceback to Detect DDoS Attack

Distributed Denial of Service (DDoS) attacks continue to pose higher threats to the internet. There are so many protocols designed to trace the attacker‟s address. We want to trace back attack source (i.e., “IP addresses”), we need to examine the tradeoff between different existing IP Trace back techniques. We developed a Novel protocol to trace the IP address of DDoS attack. The novel protocol is designed by using response 1, Nonce of secureneighbor as the parameters. We developed a sample network model. We simulate the network model by applying secure-neighbor protocol in Qualnet. Through secureneighbor, we retrieve the basic parameter value (Response 1, Nonce) and apply the decryption function on Nonce and value of neighbor-timeout to find the attackers IP address. We studied different internet topologies and aspect of DDoS attacks, used internet power low for the simulation of the internet.
