  Anonymity networks are providing practical mechanisms to protect its users
against censorship by hiding their identity and information content. The
best-known anonymity network, The Onion Routing (Tor) network, is however
subject to censorship attacks by blocking the public Tor entry routers and a
few secret Tor entry points (bridges), thus preventing users to access the Tor.
To further advance the evolution of anonymity networks, while addressing
censorship attacks, we propose to enhance the well-known multi-circuit Tor
technique with linear network coding (LNC) and analyze the resulting censorship
success. The results show that LNC can improve the robustness of Tor against
censorship.
