Abstract

Tor is the most popular anonymous communication system nowadays, that set up a excellent compromise between anonymity and performance. However, Tor is by design vulnerable to end-to-end correlation attacks. Many techniques have been and are being developed in order to mitigate these attacks. This master thesis objective is to define the utility of a new relay, and to give a measure of its contribution to the diversity of the network. This is achieved with a modified version of the TorPS , which simulate the Tor network against both relay and network adversaries. More diversity means less end-to-end correlation attacks possible by the latter. At the end, we would like the volunteers to be aware of the utility they bring to the Tor network security with a certain relay configuration.
