GNUnet seems like a very good project. Probably the best I've seen. It is a modular framework so pieces can be borrowed and built upon at many levels.

These may be naive questions (I don't know GNUnet too well), but hopefully I am about to learn something: GNUnet tries to achieve at least three goals at the same time that are not perfectly understood and should rather be treated individually: - anonymity - censor resistance - high-performance document distribution What makes you believe the GNUnet-solution for any of these aims can be factored out and used somewhere else? Also, don't the shortcomings of mix networks also apply to Freenet- / GNUnet-style anonymization schemes? In Freenet (at least in some ancient version that I once had a closer look at), I know security is even worse (though still not too bad in my eyes), because the packets don't all travel well-specified mix paths but take shortcuts. To put it more clearly: A network has "perfect anonymity" if any peer in that network can send and receive (variants: a - send only; b - receive only) packets without the contents of the packets being associated with its IP address by the adversary, and it has "high anonymity" if it has perfect anonymity in every transaction with high probability. Then I suspect that no matter what (existing) adversary model you pick, plugging a good mix network into your design on the transport layer gives you the highest anonymity possible. (And at a very good price, too: You can throw more resources at other design requirements, you get more mature anonymity technology, and you can profit from improvements in the field without changing your design at all.) Of course I'd need to define "good mix network" now. But perhaps somebody can already counter or confirm this as is? -matthias _______________________________________________ p2p-hackers mailing list p2p-hackers@zgp.org http://zgp.org/mailman/listinfo/p2p-hackers _______________________________________________ Here is a web page listing P2P Conferences: http://www.neurogrid.net/twiki/bin/view/Main/PeerToPeerConferences ----- End forwarded message ----- -- Eugen* Leitl <a href="http://leitl.org">leitl</a> ______________________________________________________________ ICBM: 48.07078, 11.61144 http://www.leitl.org 8B29F6BE: 099D 78BA 2FD3 B014 B08A 7779 75B0 2443 8B29 F6BE http://moleculardevices.org http://nanomachines.net [demime 1.01d removed an attachment of type application/pgp-signature]
