摘　　要：该文研究了概率分组标记(PPM)IP追踪机制对拒绝服务攻击(DoS)的有效性。在攻击者伪造多条攻击路径的情况下,分析得到PPM可以选取最优追踪标记概率以提高追踪效率;进一步的分析则表明,在伪造路径长度增加时,PPM效率将明显降低。Performance of IP traceback mechanisms based on Probabilistic Packet Marking(PPM) has been investigatedfor achieving traceback of DoS attacks.When there are a few forged paths,one can improve the performance of PPM by choosing marking probability carefully;but further research in this paper shows that the efficiency of PPM can be reduced obviously if the forged path length becomes longer.
