<p><b>Turtle</b> was a <a href="Free_software" title="Free software">free</a> <a href="Anonymous_peer-to-peer" class="mw-redirect" title="Anonymous peer-to-peer">anonymous peer-to-peer</a> network project being developed at the <a href="Vrije_Universiteit" class="mw-redirect" title="Vrije Universiteit">Vrije Universiteit</a> in <a href="Amsterdam" title="Amsterdam">Amsterdam</a>, involving professor <a href="Andrew_Tanenbaum" class="mw-redirect" title="Andrew Tanenbaum">Andrew Tanenbaum</a>. It is not developed anymore. Like other anonymous P2P software, it allows users to share files and otherwise communicate without fear of legal sanctions or censorship.

</p>

<div class="mw-heading mw-heading2"><h2 id="Architecture">Architecture</h2></div>

<p>Technically, Turtle is a <a href="Friend-to-friend" title="Friend-to-friend">friend-to-friend</a> (<a href="Friend-to-friend" title="Friend-to-friend">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="Peer-to-peer" title="Peer-to-peer">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.
