Role of Probabilistic Packet Marking Mechanism in Large Scale IP Trace Backs

An approach to IP trace back based on the probabilistic packet marking paradigm has been explained in this paper. Our approach, which we call randomize and link uses large checksum cords to link messages fragments in a way that is highly scalable, for the checksums serve both as associative addresses and data integrity verifiers. The main advantage of these checksum cords is that they spread the addresses of possible router messages across a spectrum that is too large for the attacker to easily create messages that collide with legitimate messages.
