funders, but I can say something about why we, the inventors of onion
routing and designers of Tor, did what we did. We were as explicit as
possible as to what we intended and why with funders, management and
others. Presumably some of it was agreeable since we received support.
The above is largely correct, so I am only clarifying where I thought
there was room for misinterpretation. The primary purpose for which
we proposed and designed onion routing networks (including Tor, which
started life in some of my NRL onion routing projects) was to separate
identification from routing, as we note in the first onion routing
publication "Hiding Routing Information" in 1996 and at
www.onion-router.net. Jim's speculation on the above cited motivation
was not something we ran across through experience but rather a design
motivation from the very beginning. We argued fifteen years ago that
to protect private traffic when going to and from a public network you
needed to carry traffic for others not just yourself, which meant that
they had to trust the network, which meant that you had to diffuse
trust by letting others run part of the infrastructure and that you
had to let them see the code. I think this is essentially stated in
our early onion routing publications. This was also part of the reason
we sought and received our first publication release for public
distribution of onion routing code in 1996. We were open source before
that phrase was in general use. My comments apply only to the funding
I received and the motivations we had. Other later goals of, e.g.,
censorship resistance and other funding of Tor I have not been part of
and should let others comment.
I like hearing the history of this project, and wouldn't mind hearing more about the challenges you faced back then, who the challengers were, and what their point of view and/or concerns were.
Paul, thank you for all your hard work!
