Dr. Mike Pound explains the mechanics of Onion Routing and how the Tor network protects user anonymity.

What goes on TOR stays on TOR, or so we hope. Dr Mike Pound takes us through how Onion Routing works.

On “How does TOR really work?”

I can only recommend the Computerphile YouTube channel. Here is the video on Onion Routing and here on the TOR Hidden Services, sometimes called the dark web. Edit: Oops, just realized that wasn't a question, but a link to an article, my bad. I'll leave this here for anyone interested.

I was watching this video explaining how tor works: link to this video It explains it with the example of 3 intermediate nodes between client and server. It says that each of the nodes can only decrypt one layer and therefore only the last node can see the message. Each node has only one key to decrypt the corresponding layer. My question is: how is that possible? How can node 2 know key2 unless it's given to it by node 1? But if node 1 sends key then it means that node one can also decrypt the second layer.
