Researchers at the University of Waterloo in Canada have developed Slitheen, a system that uses decoy routing to conceal banned websites inside of innocuous cat videos.
Decoy routing enables users to view censored websites while producing a browsing trail that looks as if they are perusing harmless sites.
Slitheen sends requests for "overt" websites with encrypted secret requests for the actual target embedded within them. Relay stations with Slitheen software installed would detect the secret requests and decode them with a secret key, and then assemble a novel package that defines the Slitheen method.
The overt site is downloaded as camouflage for the sensitive data while the target covert site is downloaded concurrently, and its contents substituted for the overt site's contents. Once this is done, the relay transmits the package back to the user that requested it.
The complex traffic generated by Slitheen is indistinguishable from a normal request.
