When the user gets the response from the server, the response message is being encrypted in a reverse manner. When the user wants to access a website(let’s say ProPublica) it encrypts the message with the respective number of layers( In our example 3 layers of encryption as three nodes are connected.) That means Layer 3(K3) can only be decrypted by Node 1, Layer 2(K2) is Decrypted by Node 2, and Layer 1(K1) is decrypted by Node 3(also called Exit Node). In this example, three nodes are taken into consideration for better understanding. First Node is called Entry Node, the last node is called Exit Node, and others are Relay Node It may be hundreds of nodes present on a network. When a user connects to Tor by using a tor client (Mostly by Tor Browser), it connects to a bunch of Tor nodes. Let’s understand In detail with an example. Onion routing is implemented by encryption in the application layer of the communication protocol stack, nested like the layers of an onion. Other backers are the Electronic Frontier Foundation, journalism and community body Knight Foundation, and the Swedish International Development Cooperation Agency, etc. It has received about 60% of its funding from the US State Department and Department of Defense. The first public release occurred a year later. Later it was changed to “Tor”, as an acronym for the former name.
The alpha version of Tor was developed by Syverson and computer scientists Roger Dingledine and Nick Mathewson and then called The Onion Routing project. TOR was originally developed by US Naval Research Laboratory in the mid-1990s to protect US intelligence communications online. Tor’s intended use is to protect the personal privacy of its users, as well as their freedom and ability to conduct confidential communication by keeping their Internet activities unmonitored. Tor makes it more difficult to trace the Internet activity to the user. It does that by bouncing internet traffic through different relays(also referred to as ‘routers’ or ‘nodes’) run by thousands of volunteers globally. It is designed to stop people( including government agencies and corporations) from learning your location or tracking your browsing habits.

The Onion Routing(TOR) is a software tool that provides Internet Security and Online Anonymity. In this article, you will learn about How You can use TOR to browse the internet anonymously. VPN does provide some level of security by hiding your IP address and location. When it comes to online anonymity and security, most people think VPN is the best way to secure your internet. When you are using an unsecured internet, your IP address is visible to everyone, and from the IP address, they can detect your current location.īased on your IP address, location, and browsing activity, they target ads.
Then you probably want to be anonymous while using the internet. Or if you don’t want big companies to track your browsing activity so that they can use it for marketing purposes.
If you live in a country where there is no freedom of speech and the government is very strict about your internet usages.
