Abstract

Lack of source authentication in the IP protocol helps to encourage denial-of-service attacks. The open and trusting nature of the protocol makes the task of identifying an attacker difficult if the attacker chooses to spoof the source address. Probabilistic Packet Marking (PPM) is an IP traceback approach that seeks to identify attackers by marking individual packets with portion of the attack path, and relies on the volume of attack traffic generated to reconstruct the whole path. In this work, we consider the fragmentation problem associated with the overloading of the identification field in IPv4 packet header in PPM implementation, and demonstrate how this can be resolved in IPv6. We show that the flow label field in the IPv6 datagram header can be safely and effectively overloaded to implement PPM schemes, and present simulation results verifying the applicability and efficiency of our approach.
