The same principle is then used to establish the communication between the entry and the second, “ middle node“.

Using the established encrypted channel, you can communicate with the nearest TOR router – called the “ entry node” in the remainder of this text. For further communication, the newly created, temporary session password is used. Then, TOR relay creates a “ session password“, encrypts it using your public key (so it can only be decrypted using your private key, not know to others, so it is safe) and sends it to your computer. You will connect to your nearest TOR relay and exchange public keys with it. To explain better, I’ll use an example, say you wish to connect to using TOR network: For establishing the connection, a system of asymmetric encryption is used, with public and private keys. These are called Onion routers (or relays). TOR network consists of a network of nodes, run on a voluntary basis. How does TOR network with Onion routing work? When the Onion routing code was released under a free license, TOR was founded as a non-profit organization, in 2006.Ģ. Scientists Roger Dingledine and Nick Mathewson joined Paul Syverson in 2002 to start what would become known as the TOR project. Onion routing was patented in 1998 by the US Navy. The development was helped by DARPA (who’s network, ARPANET, was the basis of the modern Internet). Onion routing was first developed in 1990s for US intelligence communication protection, at the US Naval Research Laboratory, by Paul Syverson, Michael G. Onion is “(multi)layered encryption”, to put it that way (I’ll explain). Tor is free, open source software for anonymous communication (in general).
