Researchers at MIT have revealed a new anonymity scheme that could rival Tor. Riffle is a mixnet, or a system that prevents traffic analysis by routing each users message through a set of servers known as mixes. Those servers, in turn, mix up the order of the messages in which they received them before passing them on to the next server. An adversary that had tracked the messages points of origin would have no idea which was which by the time they exited the last server. The system uses onion encryption, which means each message is wrapped in multiple layers of encryption.”]
