The anonymity network Tor is a solution to restore some privacy, however, Tor is slow in both bandwidth and latency. It uses a TCP-based connection to multiplex different circuits between nodes and this causes different independent circuits to interfere with each other. To solve this, we propose a transport layer implementation using the UDP-based protocol QUIC, as it allows independent streams over a single connection. We built a Tor prototype that uses this protocol and evaluated its performance using a custom network simulator, as existing simulators were shown to be incompatible. We show that the QUIC-based implementation increased performance in several of the use case scenarios, mainly outperforming on the ‘time to first byte’ metric.
