A team of researchers has created an anonymity network methodology that they believe is more efficient and more secure than existing anonymous networks such as Tor. The research team consists of computer science researchers from the Computer Science and Artificial Intelligence Laboratory at the Massachusetts Institute of Technology (MIT) and the École Polytechnique Fédérale de Lausanne in Switzerland. The anonymity architecture uses a routing protocol known as a net network, or mixnet, to make it difficult to trace communications. "Each server permutes the order in which it receives messages before passing them on to the next," according to a statement describing the secure network method. The researchers will present details of the network, named Riffle, at the Privacy Enhancing Technologies Symposium in Germany next week.
