Single-Packet IP Traceback with Less Logging

Currently, the main threats of network security are coming from hacker intrusion, deny of service (DoS), computer virus, worm, spam, malicious code and sniffer because there are many weaknesses in the original design of IPv4. One is that attackers could send IP spoofing packets which is he wants to attack. That is the attackers modify the IP from the true one to another on the IP field. However, it is hard to trace the source of attacks from victims. In this paper, we will propose a method that reduces the storage of the router and trace the attack source by a single packet. According to the experimental results, we can prove that it works well.
