摘要
近年来,网络编码以其巧妙的思想展现出生机勃勃的应用前景,但是安全问题一直是其在网络中大规模应用的最大障碍.本文分析了网络编码中存在的特有的ACK类攻击,给出了针对该类攻击的基于典型集和哈希函数以及马尔可夫模型的防御方法,并利用数据挖掘的方法获得了典型集的元素组成,同时分析了TCP流中ACK状态数的分布,展望了网络编码的发展方向.
In recent years, network coding has emerged some exciting future because of its smart technology. However, in order to let network coding become popular in the INTERNET, its security problem must be solved. Firstly, this paper gives one proposal for ACK attacks based on Typical Set, Hash Functions and Markov model, and find elements of the Typical Set using DATA Mining. Secondly, this paper analyses distribution of status for ACK in TCP stream. Finally , the open issues and challenges for network coding in the future are discussed.
