随着人们对网络隐私问题的日益关注，特别是PRISM（一个网络监控项目）的曝光，匿名通信越来越受到人们的关注。最广泛使用的匿名通信系统之一是I2P（隐形互联网项目）。与Tor（另一种流行的匿名通信系统）基于目录的方法相反，它提供了一个集中的目录服务器来管理网络的整体“视图”，I2P是完全分布式和自组织的，旨在避免攻击者枚举所有I2P的路由器。本文根据I2P的工作机制，提出了两种被动和两种主动的I2P路由器发现方法。在为期两周多的收集实验中，每天发现约25640台路由器，与官方网站公布的数据相比，几乎覆盖了I2P网络（94.9%）[1]。并在收集到的路由器的基础上，进一步对I2P网络的整体现状及其安全性做了初步的分析。结果表明，I2P网络是一个结构良好的P2P网络，但在现有的安全机制下，一些强大的攻击者仍然有可能操作多个路由器进行妥协攻击，从而破坏I2P用户的匿名性。最后，本文讨论了提高I2P网络安全性的一些对策。
With the increased focus on Internet privacy, especially after the exposure of PRISM(an Internet surveillance program), anonymous communication have been getting more and more attentions. One of the most widely used anonymous communication systems is I2P(Invisible Internet Project). And as opposed to Tor’s(another popular anonymous communication system) directory-based approach, which provides a centralized directory server to manage the overall ‘view’ of the network, I2P is fully distributed and self organizing, which aims to avoid attackers’ enumeration of all I2P’s routers. In this paper, based on I2P’s operating mechanism, we presented two passive and two active methods to discover I2P routers. In a more than two week’s collecting experiment, about 25640 routers were discovered everyday, which turned out to be an almost full coverage(94.9%) of the I2P network compared with the data announced on the official website [1]. And based on the routers collected, this paper further made a preliminary analysis of both the I2P network’s overall status and its security. The result showed that I2P is a well structured P2P network, while some powerful attackers operating several routers are still possible to perform compromise attack to break I2P users’ anonymity given the current I2P’s security mechanism. Finally, this paper discussed some countermeasures to improve the security of the I2P network.
