摘　　要：集中于针对SIP服务器的低速率拒绝服务攻击(LDoS)的研究。通过分析LDoS攻击过程中各个阶段中不同的攻击策略,建立攻击流程,并量化攻击系统的相关参数。在此基础上,构建一个生死链攻击模型,该模型采用马尔可夫链和生死过程来刻画攻击过程,通过计算平稳概率分布,来评估攻击的有效性。最后,将仿真实验结果与理论预期结果进行对比分析,实验结果表明,建立的攻击模型是有效的、可行的。In this paper,we study the low-rate denial-of-service（ LDoS） attacks against SIP server. By analysing different attack strategies in each stage of LDoS attacking process we built the attacking workflow,and quantified the relevant parameters of attack system. Based on this,we presented a life and death chain attack model. The model uses Markov chain and the process of life and death to depict the attack process,and evaluates the effectiveness of attack by calculating the smooth probability distribution. Finally,we compared and analysed the simulation experimental result with theoretical anticipated result. Experimental result shown that the attack model built is effective and available.
