The porn -- um, "privacy" -- modes in modern browsers do a great job of letting workers browse Facebook under the noses of employers with strict Web policies, but privacy modes don't do squat when a heavy-handed regime blocks access to specific websites. Freedom-loving webizens in freedom-hating countries have long turned to TOR as their onion-routing proxy of choice to get around governmental roadblocks, but researchers at the University of Michigan have developed a new system that could help Iranians and other censored Web users access "immoral" websites like Twitter and CNN.
Of course, the Telex tag couldn't be obvious or those dastardly dictators would just block all communications that contained the rerouting command. The researchers got around that by exploiting the nature of TLS handshakes that are used to transfer encrypted traffic across the Web. If you indicate that you want a Telex redirection, Telex's public key creates a steganographic tag for the traffic and inserts it into the TLS handshake's "nonce," which is normally a random string. To throw off would-be censors, the Telex tag also appears random, but the code would be recognized by the Telex servers.
