A Lightweight IP Traceback Scheme Depending on TTL

This article proposes a new type of IP traceback scheme, through recording TTL of the IP header to get the attack path, when the algorithm is in processing, you do not need to generate additional packages, so attackers could not detect the trackback happened, the scheme can be applied in at any strength of DDoS attack, solves the problem of traditional PPM algorithm failed in high strength DDoS attack, also improves the efficiency of traceback, compare with the other scheme, this scheme is simple, efficiency and robustness. So this scheme can effectively resolve the reconstruction problem. (c) 2011 Published by Elsevier Ltd. Selection and/or peer-review under responsibility of Harbin University of Science and Technology
