One of the main enablers of the Dark Web is “The Onion Router” known as TOR. An onion router system has several encryption layers intended to hide the message’s source and destination addresses. (See fig.1). Like an onion, TOR has several layers as shown in the figure. As web privacy continues to erode, TOR promises to maintain free speech and thought
Onion routing is a process for anonymous communication. TOR uses layers of encryption and a series of onion routers.
As shown in the figure – the source of the communication sends the onion to Router A. Router A then determines where to send it next by removing the first layer of encryption. Router A also sees the source address but does not know if it is the address of origination. Router A sends the remaining data to Router B. Router B removes another layer of encryption to find out where to send it next (Router C). Router C decrypts the last layer to send the data to its final destination.
Like a VPN, the secured pathway or tunnel lets users browse to public and secured Dark Web sites without conceding delicate information like IP addresses, cursor movement, your location, and other personal data stored in cookies. TOR helps to prevent deep packet analysis, and protects website data payload and header information.
