Instead he spoke volubly, on a temporary Web-based phone line, about Tor and privacy. Appelbaum himself, who is 27, was detained for several hours last summer by federal agents at Newark Liberty Airport, where he was questioned about his connection to WikiLeaks and Assange as well as his convictions about the wars in Afghanistan and Iraq.Īppelbaum said he didn’t discuss those topics with the agents in Newark, and we agreed to avoid them also. Hours earlier, Julian Assange, the brazen founder of WikiLeaks, was arrested in London on Swedish sex-crime charges. As Appelbaum put it: “Even though the government has a monopoly on violence, violence cannot solve math problems.”Īppelbaum, who is a developer for Tor and a research scientist at the University of Washington, had some cause for these sinister ruminations about governments while we spoke. This central insight of Tor is brilliantly tautological: What can’t be known can’t be found out - even by interested parties with state-of-the-art or brutal interrogation and intelligence-gathering techniques. Not only is the communication fully encrypted during transit, but its traffic pattern also is more than unknown practically speaking, it’s unknowable.

A complete chain of nodes is never fully readable at a single relay point. So why can’t a Tor transmission merely be intercepted sometime in its swerving and illogical flight path? This is the innovation of Tor’s code.

“As opposed to all the other information that comes along when you use your computer.”

With Tor, you “only reveal the information that you type,” Appelbaum says. For the person trying to get a message out through Tor, this means he communicates exactly as much as he chooses and no more. (There are some 2,000 Tor relay nodes at any one time across the globe.) The only thing the Johannesburg recipient can discover is that the data came from Tor, and Tor has successfully identified itself with no person or group, only with ideological incoherence. As Appelbaum explained, “If it’s only the military using the Tor network” - say - “it’s not anonymous.”Ī Tor transmission these days might start in Addis Ababa, hop to Dallas, then to Stockholm and finally Johannesburg. What they don’t grasp is that if Tor were cohesive - physically or ideologically - its members could be identified. Jacob Appelbaum, a developer for Tor who travels the world explaining Tor to human rights and social-justice activists, tells me that users periodically complain about the politics and motivations of other (self-identified) users. Tor is by design not a media project or a human rights one or (anymore) a military one. When a communication arrives from Tor, you can never know where or whom it’s from.

Peaceniks and human rights groups use Tor, as do journalists, private citizens and the military, and the heterogeneity and farflungness of its users - together with its elegant source code - keep it unbreachable.

The software has been downloaded more than 36 million times this year, and thousands of nameless volunteers - many of them Tor clients - now help to relay mind-bogglingly diverse Tor data in nearly every country on earth. government and other funders, the Tor Project has prolifically expanded its networks. In the past year, supported by grants from the U.S. Naval Research Laboratory introduced it at a California security conference. WikiLeaks, the swashbuckling new-media organization whose motto is “We open governments,” relies on a technology of extreme reticence called Tor Hidden Services - a part of the Tor Project, a nonprofit organization dedicated not to light and clarity but to shadows and opacity, to the increasingly difficult art of keeping secrets online.Ī deliberately byzantine system of virtual tunnels that conceal the origins and destinations of data, and thus the identity of clients, Tor has been around since 2001, when programmers from M.I.T.
