Okay I'm a bit late to this (pretty complex) thread, but here are a few
I agree GPG keys seem to be the logical basis for establishing identity and
relationships on a network of FreedomBoxes.
I think everything that has been built so far is very smart.
How do you find and connect to someone else's FreedomBox:
- My understanding from Nick's
talk<http://www.youtube.com/watch?v=zQTmnk27g9s>at the last hackfest
is that in order to establish a relationship with
someone else's FreedomBox, you need their public key and their FreedomBuddy
hidden service address (these two things together were called "identity
schema" in Nick's talk). This makes a lot of sense to me and I'm curious if
this is still the latest thinking.
- If you only have someone's FreedomBuddy hidden service address. but not
the public key, well then you can just discover the public key from the
hidden service, so yes it seems all you need is someone's .onion address to
find and connect to their FreedomBuddy.
- At some point there was talk of a global public DHT ("Neruda") for
looking up the "identity schema", but that seems redundant considering that
Tor hidden services already have a built-in DHT.
- I guess theoretically one's "personal public key" and the Tor hidden
service's public key could be the same, then you would only need a single
public key, but I'm pretty sure that's a bad idea.
- You can get someone's FreedomBuddy address in any number of ways, like
Melvin says, from your profile on the web, from a key server, from an URL
shortener, from an e-mail signature, from WebFinger, from your Skype
- In the future there could be more complex discovery mechanisms, e.g.
friends of your friends, or people who are geographically close to you, or
who like the same music :)
How do you connect to and authenticate to your own FreedomBox:
- This needs more thinking, but perhaps there should be different access
levels to your FreedomBox, not sure..
- "Trusted" access.. You sit at home in your trusted home network, or you
access your FreedomBox remotely via a trusted device which you previously
provisioned with your key. You might or might not still need to enter a
- "Restricted" access.. You sit at an untrusted place and use an untrusted
device (e.g. Internet cafe), You will definitely at least have to enter a
- Physical access.. Yes that could play a role for recovery or for
provisioning new trusted device. E.g. you're connected directly to the
FreedomBox'es wifi, or even with a cable, or you press a button, or you
read the LEDs, etc.
- Yubikey or similar physical token that you carry with you.. Might also be
useful to authenticate. The Yubikey could be plugged directly into the
FreedomBox'es USB port. Or your could take it to the Internet cafe and
copy&paste its one-time-password password into your FreedomBox'es web
interface to access it.
- I think a public DNS, IP and reverse proxy service (with TLS) such as
PageKite (as Michiel describes) makes a lot of sense.
- You don't need this if you sit at home and if all you want is your
FreedomBox to talk to someone else's FreedomBox, but you do need the
reverse proxy for two other purposes.
- To easily access your FreedomBox and use its services remotely, when
you're at the Internet cafe (but then you probably want stronger
authentication, e.g. with Yubikey, or alternatively more restricted access).
- To expose your FreedomBox to the Internet and make it a server in the
existing client/server landscape. E.g. turn it into a Diaspora node,
Unhosted "remoteStorage", webserver, XMPP server, etc.
- I agree there's a lot in there we can learn from. I think especially
Hosted Linked Data and a SPARQL service should be part of the FreedomBox at
- I admire Henry Story's work, but I don't think WebID is ready for
end-users. Working with client certificates in your browser, getting them
into your (several) browsers, recovering them, etc. is way too complicated.
- I do think however the WebID mechanism could be useful for communication
between FreedomBoxes, rather than between user and FreedomBox.
- E.g. once we start building a super cool semantic Linked Data / SPARQL
application on the FreedomBox, then WebID could be the way to authenticate
one box to the other (after they establish their FreedomBuddy relationship).
