Peer-to-Peer Rendezvous System for Minimizing Third Party Visibility and Method Thereof

Abstract

A method and system for enabling peer-to-peer (P2P) communication between a first device and a second device is disclosed. According to one embodiment, a P2P communication system includes a first peer agent serving a first peer, a second peer agent serving a second peer, and a rendezvous server. The rendezvous server updates a first IP address for the first peer agent to the second peer agent and a second IP address for the second peer agent to the first peer agent. The first peer agent and the second peer agent communicate with the rendezvous server by dropping and retrieving a plurality of dead-drop packages. A first dead-drop package of the plurality of dead-drop packages comprises a first alias that is known only to the first peer and the second peer. A second dead-drop package of the plurality of dead-drop packages comprises a second alias that is different from the first alias.
