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. https://github.com/akwizgran/adtn http://sourceforge.net/p/adtn/mailman Cheers, Michael -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (GNU/Linux) iQEcBAEBAgAGBQJSVpetAAoJEBEET9GfxSfMaJEH/iMdicp88t1+euSXpDW8FAEn py+0ZjxPL2haJN4BKKY17qzP8hA9Qk07RSzex22PFzastczcfGTRHen7R5VWCckd Ti0QuDaJCtGXrl3JGeKhsPwDYh7UR4/pe3n0GwJz5zemwMsIQNRYAMLrJJmwlU7M 4C+zd9x9j+jXtJvOpoGzfEcnNUfBq0I/NfQZ+hVDHBuu351R0nzskswj6NvgPFT4 4a0QRQ9Oljv7Fca9j/HG1RPMatMYl/qGOR0UrlJoE/x8VM1NEHoZbzP75ldm3dom mrbRc+LMCIaSJ4cK2SShIVSb/GDG+M/rYZj6T79+KsfjFJAXcG7VuXatZy3Nr1A= =vK8q -----END PGP SIGNATURE----- _______________________________________________ Guardian-dev mailing list Post: Guardian-dev@lists.mayfirst.org List info: https://lists.mayfirst.org/mailman/listinfo/guardian-dev To Unsubscribe Send email to: Guardian-dev-unsubscribe@lists.mayfirst.org Or visit: https://lists.mayfirst.org/mailman/options/guardian-dev/eugen%40leitl.org You are subscribed as: eugen@leitl.org ----- End forwarded message ----- -- Eugen* Leitl <a href="http://leitl.org">leitl</a> http://leitl.org ______________________________________________________________ ICBM: 48.07100, 11.36820 http://ativel.com http://postbiota.org AC894EC5: 38A5 5F46 A4FF 59B8 336B 47EE F46E 3489 AC89 4EC5
