摘　　要：Tor匿名网络,作为目前互联网中最成功的公共匿名通信服务,在保护用户隐私信息的同时,为不法分子滥用以从事网络犯罪活动,成为暗网空间的重要组成部分。身份的隐藏给网络空间的管控带来了严峻的挑战,使Tor匿名网络的反制方法成为匿名通信领域研究的热点。在介绍了Tor匿名网络基本原理的基础上,对其攻击技术展开系统而完整的综述。根据被攻击的弱点是否来自Tor协议内部,将主流的攻击技术分为两类。基于流量分析的攻击将匿名网络看作黑盒,具有较高的隐蔽性与适用性,而基于协议弱点的攻击利用Tor网络内部的弱点发起更迅速、更有效攻击。本文归纳比较了各种攻击技术的原理及优势,并对未来匿名网络的发展趋势进行了展望。The Tor anonymous network is one of the most successful public anonymous communication services in the Internet.Although Tor is designed to protect users＇ private information,it is often abused by law breakers to conduct cybercrimes without been traced.The anonymity nature of Tor brings serious challenges to the management and control of cyber space,which motivates active research of countermeasures to Tor anonymous network.In this paper,we first study the mechanism of Tor anonymous network,and then we present a systematic and comprehensive survey on the attack technologies to Tor.Representative attack technologies to Tor can be classified into two categories,based on whether the explored vulnerabilities come from the protocol lever of Tor or not.The traffic analysis- based attacks,which treat the network as a black box,are often stealthier and with more applicability.The protocol vulnerability-based attacks can be initiated more rapidly and effectively because they exploit the weak points within the Tor network itself.This paper summarizes the basic principles of various attack techniques and compares their pros and cons.The future development trend of anonymous networks is discussed.
