基于网络行为匿名特征的Tor网络匿名度分析
Research on anonymity degree of Tor network based on anonymity characteristics of network behavior
摘要
Abstract
Tor can provide high quality anonymous service,the research on Tor anonymity metrics at present is mainly based on system design and information entropy,it is a static model which can hardly describe the anonymity of Tor in different environment with specific network behavior dynamically.Therefore this paper proposed a dynamic anonymity metrics model based on network behavior anonymity characteristic,which could improve extant anonymity metrics' matter of narrow application range,and could provide the theoretical basis for anonymous users to evaluate the anonymous network.And then it proves this anonymity metrics has superiority through experiment.On the basis of this,it took clogging attack for example,and analysed how much anonymity Tor could achieve under the malicious server sent burst flow to clog the network.At last,it comes to a conclusion that clogging attacks can have a certain extent effects on Tor's anonymity.关键词
