How does tor work?
The onion router (Tor) is a web browser that provides better security and privacy to its users. It can perform all the functions of a traditional browsing application while keeping its users anonymous.
How does tor work?
Tor browser, as the name suggests, works on the onion routing protocol. It encrypts the message in layers of encryption and sends it over several
Onion routing
The working of the onion routing is described as follows:
First, we generate a request that they want to send to a server, such as Google, over the tor network.
We then decides the three relays that they want to use to route this request, for example
We acquire the public keys to these three relays (
). We encrypt the message
using google's public key and obtain the encrypted message We encrypt the
using the public key of the third relay and obtain We encrypt the
using the public key of the second relay and obtain We encrypt the
using the public key of the first relay and obtain the final message We then sends
to the first relay. The first relay removes the last layer of encryption (that was encrypted using its public key) by decrypting it with its private/secret key
and obtains The second relay removes the second last layer of encryption and sends the resulting message
to the third relay, which then removes the third last layer of encryption and sends the resulting message to the destination (google). Google then decrypts the message it received
and obtains the actual message Server/google then processes the request and sends a response to the user and follows the same process.
It sends the packet to
which encrypts the message with its private/secret key. then sends it to which encrypts the message with its private/secret key. then sends it to which finally routes the packet to the user.
The user then removes all the layers of encryption and views the final response.
