站点指纹模型训练系统FMTS的设计与实现

Design and Implementation of Fingerprint Model Training System for Web Site

基于指纹识别的匿名攻击原型系统用于度量攻击的复杂程度,定量评估匿名Web浏览系统的匿名性,提供实验平台。作为其重要组成部分,站点指纹模型训练系统(FingerprintModelTrainingSystem,FMTS)用于遍历目标站点的网页,抽取页面指纹及链接关系构造形成站点指纹模型。文中介绍了指纹模型训练系统的总体设计方案以及关键实现技术。并针对系统的一个实际运行结果———中南大学网站(www.csu.edu.cn)的指纹模型,分析了其“指纹”分布情况。

Fingerprint-based Anonymity Attack Prototype System(FAAPS)is a platform for measuring the complexity of traffic analysis attack and evaluating anonymity of anonymous browsing system.Fingerprint Model Training System(FMTS)is an important part of FAAPS.In this article,a design scheme of FMTS is proposed.Key issues related to traversing Web Site,extracting fingerprint and link structure are investigated.Moreover,a practical running result,fingerprint model for Web site www.csu.edu.cn,is studied thoroughly with respect to the fingerprint distribution.
