A subset of the internet where communications between two parties or client-server transactions are obscured from search engines and surveillance systems by layers of encryption. The U.S. Navy designed the original Darknet by developing The Onion Router network, or TOR, back in the 1990s. Roger Dingledine and Nick Mathewson deployed the first alpha implementation in 2002 with some initial funding by the Electronic Frontier Foundation (EFF.) The TOR Project became a non-profit in 2006 and is funded by the U.S, Sweden, different NGOs, and individual sponsors.
