Four layers of encryption protect your traffic when using Onion over VPN, while only three layers of encryption are applied when using the Tor browser alone.Ĭonnecting to a VPN before using the Tor network provides an additional layer of privacy and security compared to using the Tor browser alone. Put simply, the VPN server acts as an extra node in the data transfer. The Tor exit node is able to see the contents of your browsing data, but it does not know the VPN IP address. At the exit node, your traffic is decrypted before it reaches its final destination.At each node, a layer of encryption is removed. This adds three additional layers of Tor encryption. As your traffic travels through the Tor network, it is bounced through three ‘nodes’ in different locations: the guard node, the middle node, and the exit node.Your browsing traffic is decrypted once it leaves the VPN server, though it still carries the VPN server’s IP address.This adds an additional layer of privacy. If you use the Tor browser while connected to the VPN, the guard node (the first Tor node) will see the IP address of your VPN server instead of your own public IP address.

Each node in the relay only knows the next node it has to reach and does not know the entire path. In a Tor network communication from the source to the destination follows a circuitous path to avoid tracking. Authorized and unauthorized persons can read the traffic between the sender and receiver by looking at the packet headers. Various traffic analysis tools and network monitoring tools exist to sniff traffic and study user habits. While the ‘payloads’ can be encrypted the ‘headers’ are not and these contain information about where this packet originated, where is it headed, its size and timing and so on.
All packets have a ‘payload’ and a ‘header’. An individual’s digital footprint can easily be ascertained by looking at the ‘packets’. How does Tor work?ĭata that is passed through the Internet is divided and these are known as ‘packets’. Once inside the ‘Deep web’, websites comes with different URLs that end with a suffix ‘.onion’. (More Indians are logging on anonymously using browsers like Tor, Freenet, I2P and Tails ) According to some statistics, there are 500,000 to 1 million individuals from India browsing the deep web every day. There is no accurate estimate of how deep the “The Deep web” actually is but is expected to be 500 times the size of the surface web. This is the reason that ‘Tor’ is sometimes used for legal and illegal purposes. But by using browsers like ‘Tor’, the location of users is concealed and conversations are private. Most conversations outside the “Deep web” can be tracked and spied upon. The Tor software was originally written in the ‘C’ programming language and has 340,000 lines of source code.

It is free software that is available for Windows, Linux/Unix, Mac and Android operating systems. It was first developed by United States Naval Research employees and further developed by DARPA (Defense Advanced Research Projects Agency) in 1997. ‘Tor’, ‘ The Onion Router’ is a set of volunteer servers that is designed to keep traffic analysis private and untraceable. We will discuss ‘Tor – The Onion Router’ in this post. In addition, ‘The Deep web’ is not indexed by search engines and hence does not turn up in search results. This is possible with browsers like Tor, Freenet, I2P and Tails. The “Deep web” was earlier only associated with criminal activities but that may be changing with a new set of extremely privacy conscious individuals who also seek anonymity while surfing. “Deep web” or the “Dark net” is the place where there is no Internet surveillance.
Customer data is another new gold and grabbing it is the necessity of the day. Social media keeps us all firmly wrapped in its arms and life is as usual on the net oblivious to the many “virtual eyes”.
