Hi Johan, I don't think concealing your IP address would protect you against rocket attacks. As far as I know, there are two ways to locate a satellite phone that have nothing to do with its IP address. The first is radio triangulation. The second is the GPS location that the phone transmits when it connects to the satellite. However, for less extreme situations I'm still interested in the problem of publishing your IP address so that only trusted people can retrieve it. One possibility would be to publish your IP address in a DHT under a key known only to yourself and the trusted people (or you might use a different DHT key for each trusted person). But the DHT nodes would be able to see which IP addresses were retrieving which other IP addresses, so they'd be able to map the social network. To prevent that, you could encrypt the IP address before storing it in the DHT - but the DHT nodes would still be able to see which IP addresses were retrieving encrypted data published by which other IP addresses. To prevent /that/, everyone could access the DHT through an anonymity system such as Tor - but in that case you might as well publish your IP address through a Tor hidden service and forget about the DHT. And that looks a lot like FreedomBuddy. :-) Cheers, Michael -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (GNU/Linux) iQEcBAEBAgAGBQJRESnQAAoJEBEET9GfxSfMAzYIAIQS8Hr35cp8dGyhdPYKo8xN 76VWHyZyG/wpR7ihLsuipt3KtdXYl8LIUCIaYh6s3ZgXZgLFSTJqGcTosDf+ho9D cqW4KiEJ5lUii5u0L5BfDYDy7rl9gFqsPomBjg4T+s2GzXZwyTf0jYPtVZ2FuAAP yNwDDwW240AeSTfr2MAWdDd/Ln2sZGrG5AlmszkNvMYEnRuvxtmP50IZkdKHgXTO ixOexWVk9l8FFlPF0hYZQkxzJz9pC+ZpNvhVAMQPmfIojTjOrYJm0k+w3A1TPcqC ZAnU+KekBINFUOx5LVAG34GLLIPWQCIl9FNbwnZM3QIXYTUaAW0D0zueGHB1x9U= =deBw -----END PGP SIGNATURE----- _______________________________________________ Freedombox-discuss mailing list [email protected] http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/freedombox-discuss
