We model and analyze passive adversaries that monitors Tor traffic crossing the border of a jurisdiction an adversary is controlling. We show that a single adversary is able to connect incoming and outgoing traffic of their border, tracking the traffic, and cooperating adversaries are able to reconstruct parts of the Tor network, revealing user-server relationships. In our analysis we created two algorithms to estimate the capabilities of the adversaries. The first generates Tor-like traffic and the second analyzes and reconstructs the simulated data.

攻击者监控穿越其管辖边界的 Tor 流量并重建 Tor 电路

我们对被动对手进行建模和分析，这些对手监控穿越对手控制的辖区边界的 Tor 流量。我们表明，单个对手能够连接其边界的传入和传出流量，跟踪流量，并且合作的对手能够重建 Tor 网络的一部分，揭示用户-服务器关系。在我们的分析中，我们创建了两种算法来估计对手的能力。第一个生成类似 Tor 的流量，第二个分析和重建模拟数据。
