匿名网络Tor面临的一大难题是流量相关攻击，NSA或其它类似机构可以通过长期的流量模式识别出Tor用户。德国Max Planck研究院的研究员Stevens Le Blond正在开发一个替代的匿名网络Aqua（PDF），设计能抵御流量相关攻击，通过仔细分析时机、以及混合少许虚假流量，进出Aqua网络的流量是不可区分的。不过Aqua 的设计还没有在可用的软件上成功实现，而到目前为止还只能保护文件共享而不是任何类型的网络数据。因此，尽管Tor存在许多缺陷，它仍然是唯一能匿名网络流量的实用工具。为了增强防御流量相关攻击的能力，Tor项目正尝试大幅调整网络的工作原理。This entry passed through the Full-Text RSS service — if this is your content and you're reading it on someone else's site, please read the FAQ at fivefilters.org/content-only/faq.php#publishers.
