Onion routing research began in 1995 by David Goldschlag, Michael Reed, and Paul Syverson, with one goal in mind, which was to separate identification from routing. Tor works in conjunction with HTTPS, therefore the two methods combined provides end-to-end encryption of data, and protection by cloaking client and destination communication, as well as the locations of both ends. HTTPS provides end-to-end encryption of data so that in case an attacker is spying on the network, that attacker is not able to decrypt the information and figure out what is being transmitted. HTTPS (Hypertext Transfer Protocol over TLS) is a secure communication protocol used widely in the Internet, which provides authentication of accessed websites and provides privacy of the data that is exchanged between the client, web server, and the website. Nowadays many sites are sent through protocols such as HTTPS in order to protect a user's privacy. In this way, Tor protects users from attackers who spy on a network and try to steal a user's information. Also while in the Tor network, client traffic is encrypted by Tor. While a client's traffic traverses through the Tor network, the origin of the traffic becomes no longer known, and the final destination is only known at the exit point of the Tor network. The Tor network is a system of relays that passes around a client's traffic before sending the traffic to the client's actual destination. Tor is an anonymity network that is volunteer-based, where the users of the Tor network can become part of the network to increase its size and randomness. However as the Internet continues to become more expansive and accessible, the attacks on people using the Internet by spying on and stealing their information also increases. Today we live in a world where the Internet is accessible from almost anything that we have in our possession. If you're not sure if you have those skills, you may want to try Lab Zero first. You should have already uploaded your SSH keys to the portal and know how to log in to a node with those keys. To reproduce this experiment on GENI, you will need an account on the GENI Portal, and you will need to have joined a project. This experiment will take approximately 30 minutes to setup, and another 20 minutes to test the network. We will be examining the traffic to see the functions of Tor, specifically what information can and cannot be seen when passing traffic through the Tor network. In this experiment, we will be setting up a private Tor network on GENI, and will be testing this network by listening on the traffic going through the network.
