![]() ![]() Beresford from the University of Cambridge, used the Loopix mix network to validate their work. The Rollercoaster developers, Daniel Hugenroth, Martin Kleppmann, and Alastair R. To minimize latency, Tor nodes forward packets as quickly as they can, which may help eavesdroppers correlate the traffic. It relies on the difficulty of tracking messages through that path, but a sophisticated and well-placed adversary can do various kinds of traffic analysis to potentially match up traffic between two endpoints, thus drawing conclusions about the participants in the communication. Tor uses multiple relay nodes, each of which only knows its predecessor and the node to pass the message on to. Rollercoaster is a recently announced mechanism that extends the functionality of mix networks in order to more efficiently communicate among groups. ![]() Tor is perhaps the best-known mix network, but there are others that make different tradeoffs to increase the security of their users. Mix networks are meant to hide that metadata by routing packets through various intermediate nodes to try to thwart the traffic analysis used by nation-state-level adversaries to identify "opponents" of various kinds.
