Researchers from MIT and EPFL claim they might have a better and moe secure network than Tor. They've developed an anonymity network, Riffle, that promises to maintain privacy so long as at least one server is safe.
The secret is the use of a mixnet, where servers switch the order of messages as they're received, but without using relatively inefficient public keys. Instead, Riffle relies on a verifiable shuffle across all servers for the initial connection, and authentication encryption for the rest. In essence, even compromised servers can't mess things up -- they have to shuffle messages correctly for the good servers to accept the incoming data.
The technique is extremely efficient, to the point where transferring takes a tenth of the time that it would on a conventional anonymity network.
