BitTorrent Creator's New Software DissidentX Hides Secrets In Plain SightScreen Shot 2014-01-15 at 2.46.49 PM
Bram Cohen, inventor of BitTorrent and now the steganography tool DissidentX.
Encryption tools help people keep secrets. Bram Cohen has a more subtle ambition: he wants to help people keep secret the act of keeping secrets.
For the last year Cohen, who created the breakthrough file-sharing protocol BitTorrent a decade ago, has been working on a new piece of software he calls DissidentX. The program, which he released over the summer in a barebones prototype and is now working to develop with the help of a group of researchers at Stanford, goes beyond encryption to offer users what cryptographers call “steganography,” the ability to conceal a message inside another message. Instead of merely enciphering users’ communications in a scramble of nonsensical characters, DissidentX can camouflage their secrets in an inconspicuous website, a corporate document, or any other, pre-existing file from a
Rick Astley video to a digital copy of Crime and Punishment.
“What you really want is to be as unsuspicious as possible,” says Cohen, who spoke with me about DissidentX at the Real World Crypto conference in New York Tuesday. “We don’t want an interloper to be able to tell that this communication is happening at all.”
