[guardian-dev] ADTN: Anonymous Delay-Tolerant Network

Hi all,

Ana Barroso gave an exciting presentation at CTS IV about a new idea
for anonymous communication. Briefly, the idea is to use short-range
communication between mobile devices to create a delay-tolerant
network. Any member of the network can send messages anonymously to
the whole network, and members who know each other can use the network
to exchange end-to-end encrypted private messages.

An adversary who can observe the whole network and participate in it
can't tell:

* Which users are sending messages, as opposed to just forwarding them
* Which user is the source of an anonymous message
* Which users are the source and destination of a private message
* Which users know each other

These are strong anonymity properties that are clearly applicable to
activist use cases, so I'd like to see this thing built. It does't,
unfortunately, follow that I can build it on my own, but with our
collective skills, experience and fragments of reusable code I think
we can put together a proof-of-concept Android app with minimal risk
of karoshi.

I've set up a Github project and a couple of mailing lists. Please
join the adtn-devel list if you'd like to discuss or contribute to the
project, or the adtn-announce list for occasional updates. Ana's
working on a tech report that will describe how her idea works.

Looking forward to your comments, suggestions and pull requests.
