Extending Trust in Peer-to-Peer Networks

This paper presents a way of reducing the risk involved with downloading corrupt content from unknown (and hence untrusted) principals in a P2P network. This paper gives a brief overview of the need for trust in P2P networks, introduces a new notion called trust*, and shows how this may be used in place of the conventional notion of trust. Finally, we apply trust* to the Turtle P2P client and show how the integrity of downloaded content can be guaranteed without assuming that trust is transitive.
