Turtle F2F
open-in-new
<h2 id="architecture">Architecture</h2> <p>Technically, Turtle is a <a href="/facts/Friend-to-friend/ldUJUhBW">friend-to-friend</a> (<a href="/facts/Friend-to-friend/ldUJUhBW">F2F</a>) network - a special type of peer-to-peer network in which all your communication goes only to your friends, and then to their friends, and so on, to the ultimate destination. </p><p>The basic idea behind Turtle is to build a <a href="/facts/Peer-to-peer/wCCdPb0H">P2P</a> overlay on top of pre-existing trust relationships among Turtle users. Each user acts as node in the overlay by running a copy of the Turtle client software. Unlike existing P2P networks, Turtle does not allow arbitrary nodes to connect and exchange information. Instead, each user establishes secure and authenticated channels with a limited number of other nodes controlled by trusted people (friends). </p><p>In the Turtle overlay, both queries and results move hop by hop; the net result is that information is only exchanged between people that trust each other and is always encrypted. Consequently, a snooper or adversary has no way to determine who is requesting / providing information, and what that information is. Given this design, a Turtle network offers a number of useful security properties, such as confined damage in case of node compromise, and resilience against denial of service attacks. </p> <h2 id="see-also">See also</h2> <ul> <li>Free and open-source software portal</li></ul> <ul><li><a href="/facts/GiFT/PTXdHz5q">giFT</a></li> <li><a href="/facts/Internet_privacy/Fdnjfnds">Internet privacy</a></li> <li><a href="/facts/File_sharing/7GISy0GJ">File sharing</a></li> <li><a href="/facts/Friend-to-friend/ldUJUhBW">F2F</a></li> <li><a href="/facts/RetroShare/R6y2tImA">RetroShare</a> (inspired by "Turtle Hopping" feature)</li></ul> <ul><li><a href="http://turtle-p2p.sourceforge.net/turtleinitial.pdf">http://turtle-p2p.sourceforge.net/turtleinitial.pdf</a> "Safe and Private Data Sharing with Turtle: Friends Team-Up and Beat the System"</li> <li><a href="http://www.usenix.org/events/sec05/wips/popescu.pdf">http://www.usenix.org/events/sec05/wips/popescu.pdf</a> "Turtle: Safe and Private Data Sharing" from Usenix 2005 conference</li> <li><a href="http://delis.upb.de/paper/DELIS-TR-169.pdf">http://delis.upb.de/paper/DELIS-TR-169.pdf</a>[<i>permanent dead link</i>] from the "Applied Public Key Infrastructure: 4th International Workshop: Iwap 2005"</li> <li><a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/&toc=comp/proceedings/icpads/2005/2281/01/22811toc.xml&DOI=10.1109/ICPADS.2005.215">http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/&toc=comp/proceedings/icpads/2005/2281/01/22811toc.xml&DOI=10.1109/ICPADS.2005.215</a> from the "11th International Conference on Parallel and Distributed Systems (ICPADS'05)"</li></ul>
