摘要

重点关注Tor匿名通信系统的家族（family）设计，从连续两年的Tor网络真实数据中提取了数千个Tor节点家族，揭示了Tor节点家族的规模、带宽、地理分布等规律，同时也研究了超级家族背后的运营者身份。基于测量结果的分析验证了Tor的家族设计在保障其匿名性方面所发挥的不可替代的重要作用。相应的安全性分析说明了恶意Tor节点家族对Tor网络可用性带来的挑战，也揭露了Tor网络中隐藏家族现象的普遍性及其对Tor网络匿名性所造成的威胁。

Abstract

Tor family was focused on design and given a family-level measurement of it.Based on Tor node families (over 3000) discovered from live Tor network data (from Jan.2011 to Dec.2012)

a few characteristics of Tor node families were revealed

such as family size

bandwidth

geographical distribution as well as operators providing a few big families.The analysis validated the irreplaceable role played by family design in enhancing Tor’s anonymity.Based on the measurement

security analysis showed the serious availability threat a compromised node family can cause to the Tor network.Besides

It also discussed Tor hidden families and the potential anonymity risk caused by them.
