Iran blocked Tor handshakes using Deep Packet Inspection (DPI) in January

2011 and September 2011. Bluecoat tested out a Tor handshake filter in

Syria in June 2011. China has been harvesting and blocking IP addresses

for both public Tor relays and private Tor bridges for years.

Roger Dingledine and Jacob Appelbaum will talk about how exactly these

governments are doing the blocking, both in terms of what signatures they

filter in Tor (and how we've gotten around the blocking in each case),

and what technologies they use to deploy the filters -- including the

use of Western technology to operate the surveillance and censorship

infrastructure in Tunisia (Smartfilter), Syria (Bluecoat), and other

countries. We'll cover what we've learned about the mindset of the censor

operators (who in many cases don't want to block Tor because they use

it!), and how we can measure and track the wide-scale censorship in these

countries. Last, we'll explain Tor's development plans to get ahead of

the address harvesting and handshake DPI arms races.

Tocmai l-am vazut, e ceva ce trebuie vazut, ce s-a intamplat in Iran, China, Siria, Tunisia, Egipt se poate intampla si la noi, si e bine sa stim ce se intampla, ce se poate face pentru monitorizarea traficului.
