Hi George,
Where can I find the BAR paper referenced on [1]? It would help me
understand some of your decisions and threat model better. I also will
need to cite it in my own papers.
You might also be interested in Clique [2], which I published July 4 and
announced on this list August 4. Your feedback on that would be
splendid, although I need to write a paper with some better
explanations. A short comparison, as I understand things:
1. Both of us made very poor choices when we named our protocols. How
on earth is someone to find us on a search engine?
2. BAR communicates via an anonymity network like Tor (?) Clique is
not an anonymity protocol; it is a metadata privacy protocol.
3. BAR aims to provide low latency. Clique is intended to be a little
faster than U.S. Mail.
4. BAR's per-network scaleability limit is a few hundred nodes. Clique
is intended to be "good" at 30,000 nodes and "fair" at 1,000,000 nodes.
5. BAR costs "a few Mbps" of bandwidth. Clique hasn't even been tested
that fast, but is designed to consume roughly one VOIP channel's
bandwidth equivalent in common use.
6. BAR appears to be written in... Python? Clique had a Python
implementation, but it proved unwieldy. Its reference implementation is
written in C.
7. BAR's user interface is ... not known to me. Clique's user
interface /doesn't exist/ today, although sample scripts are provided.
8. BAR's encryption is ... well, I'm not sure. Clique's encryption is
a little nonstandard and a little controversial.
9. Does BAR work on mobile devices? Clique does not work natively on
mobile devices, although workarounds exist if a user can arrange for a
secure non-mobile node.

Hi everyone,
We released a TL;DR guide on broadcast anonymity [1] that i think you'll find
interesting.
