摘要: 概率包标记(PPM)是对拒绝服务(DoS)攻击进行IP追踪的一种实用而有效的方法。文章提出通过利用TTL域对原有PPM方案进行改进,减少了路径重构所需的数据包数量,提高了路径重构的效率。

关键词: IP追踪, 分布式拒绝服务, 概率包标记, TTL

Abstract: Probabilistic packet marking(PPM)is a practical and effective method for IP traceback of denial-of-service(DoS)attack. The probabilistic packet marking scheme is improved by using TTL, and the new scheme can decrease the number of packet the path reconstruction needs, and can increase the efficiency of path reconstruction.

Key words: IP traceback, Distributed denial of service(DDoS), Probabilistic packet marking, TTL
