A group of researchers has developed Riffle, a new anonymity scheme that provides better security and performance than others, including Tor. MIT researchers have created the new anonymity network, which promises to solve weaknesses of the most popular Tor architecture. Each server permutes the order in which it receives messages before passing them on to the next. Messages are encrypted hop by hop while travelling from source to the final recipient. An attacker is not able to track messages because the paths of each message are random.”]
