摘要: 防御拒绝服务(DoS)攻击是目前最难解决的网络安全问题之一。概率包标记(PPM)是一种比较有效且实用的解决方法。然而大多数PPM方案都存在最弱链问题,导致了弱收敛性。提出一种新的补偿概率包标记方法,有效地减小了重构路径时的收敛时间以及计算开销,提高了路径重构的效率。

Abstract: Denial of Service attack is among the hardest network problems.Probabilistic Packet Marking(PPM) is an efficient and practical scheme.However,there exits the weakest link problem in most schemes and this problem causes the poor convergence.A new scheme of PPM with compensation for IP traceback is presented in this paper.The convergent amount of marked packets required for path reconstruction and the computation overhead are both efficiently improved,and the efficiency of path reconstruction is increased.
