Tarzan is a peer-to-peer anonymous IP network layer.
Many P2P systems try to implement anonymity at the application layer,
instead of at a lower-level network layer. A robust free infrastructure
which can anonymize any Internet traffic would benefit a wide array of
existing protocols and current p2p systems, since the anonymous connection
could seamlessly replace the current connection.
Main designs goals of Tarzan, ordered by priority:
7 Application independence: Tarzan should provide the abstraction of an IP
tunnel and perform transparently to user applications.
7 Anonymity against malicious nodes: Tarzan should ensure that colluding
nodes cannot link a participating host as the sender (or recipient) of any
message.
7 Fault-tolerance and availability: Tarzan should resist an adversary's
attempts to overload the system or to block system entry or exit points.
Tarzan should minimize the damage any one adversary can cause by running a
few compromised machines.
7 Performance: Tarzan should maximize the performance of tunnel
transmission, subject to our anonymity requirements.
7 Anonymity against a global eavesdropper: An adversary observing the
entire network should be unable to determine which Tarzan relay initiates a
particular message.
