any thoughts on this?
It's totally true that the military people who invented Tor were
thinking about how to create a system that would protect military
communications. The current iteration of that is described at
https://www.torproject.org/about/torusers.html.en#militaryright on the Tor home page.
However, the Tor developers also became clear early on that the
system wouldn't protect military communications well unless it had
a very diverse set of users. Elsewhere in that same e-mail
discussion, Mike Perry (a current Tor developer) alludes to this:
https://lists.torproject.org/pipermail/tor-talk/2011-March/019898.html In fact, the best known way we have right now to improve anonymity
is to support more users, and more *types* of users. See:
http://www.freehaven.net/doc/wupss04/usability.pdf http://freehaven.net/~arma/slides-weis06.pdfThe first link is to a paper called "Anonymity Loves Company", which
explains the issue this way:
No organization can build this infrastructure for its own sole use.
If a single corporation or government agency were to build a private
network to protect its operations, any connections entering or
leaving that network would be obviously linkable to the controlling
organization. The members and operations of that agency would be
easier, not harder, to distinguish.
Thus, to provide anonymity to any of its users, the network must
accept traffic from external users, so the various user groups can
blend together.
You can read the entire (ongoing) discussion about government funding
for Tor development via
