Mozilla 加入 Tor Relay 的行列

Mozilla 宣佈了他們提供硬體與網路,提昇 Tor 的隱私性:「Deploying tor relays」。可以在「Results for mozilla」這邊看到這一波有十二台上線了。

架構上完全獨立於目前的 production 環境 (所有的硬體與網路設備),這是 Mozilla 提供的網路架構說明:

另外關於安全以及隱私性的部份,他們也提供了不少意見與說明。

像是單一組織不應該提供太多 bandwidth,這可以當做是避嫌:

A single organization shouldn’t be running more than 10Gbps of traffic for a middle relay (and 5Gbps for an exit node).

一個 Tor 節點需要兩個月的時候逐漸讓整個網路使用:

A new Tor instance (identified by its private/public key pair) will take time (up to 2 months) to use all its available bandwidth.

目前 Tor 的程式效能限制:

A Tor process (instance) can only push about 400Mbps.

這是 Tor 的安全限制:

A single public IP can only be shared by 2 Tor instances

這是避開防火牆的限制:

Listen on well known ports like 80 or 443
