摘要/Abstract

摘要： 首先对CSMA/CA机制进行形式化建模，然后基于马尔可夫链从随机性能模型和带宽占用模型两方面给出了对其进行攻击的理论分析，在此基础上给出了对CSMA/CA机制的具体攻击方法。在仅掌握数据帧部分字段的情况下对接入机制攻击进行了实验，并对吞吐量、通信效率、碰撞次数几方面进行了性能分析。实验结果验证了利用马尔可夫链理论对CSMA/CA机制进行攻击分析的可行性和有效性。

Abstract: The CSMA/CA mechanism was formally modeled firstly. Based on the Markov Chain theory, the analysis of attack on CSMA/CA is introduced from two aspects, such as the stochastic performance model and bandwidth share model. After discussing the typical in frames. I}he attack performance attack methods, the experiments was performed with the knowledge of partial fields was analyzed by throughput, communication efficiency and collision numbers, which validated the feasibility and efficiency of attack method based on Markov Chain theory.

Key words: Markov chain, CSMA/CA, Access mechanism attack
