The graph above comes from the document "HIding Router Information", used to formally present the concept of 'Onion Routing' at a convention in Cambridge in 1996.
I am analysing this graph for university research and have a number of questions:
At the dawn of 'Onion Routing', was the layered encryption similar to the one Tor uses today, or has there been any substantial change?
In this graph, is the information between the client (Initiator Machine) and the first node (W) encrypted, or is it the first node that encrypts the information? Who currently initiates layered encryption on the Tor network, the first node, or Tor Browser from the client device?
The graph says that the first node (W) is controlled by "Secure Site". I have read the document "Hiding Router Information" and I am not sure what "Secure Site" is. Does anyone know?
Sorry about the writing. But English is not my mother tongue.
