Re: [tor-relays] Node Operators Web Of Trust
Technically, you can try doing the oder way around: sign you PGP key with a private key of your tor node. Thus, you can prove, that you own the node. 10.11.2014, 13:58, "Gareth Llewellyn" gar...@networksaremadeofstring.co.uk:On Fri, Nov 7, 2014 at 8:26 PM, grarpamp grarp...@gmail.com wrote:Is it not time to establish a node operator web of trust?

As an operator you would either - sign with your key a statement of node fingerprint into a notary service - create a subkey of your key holding said statement in comment - sign your key by node key if security of node key was better https://trac.torproject.org/projects/tor/ticket/9478 But since the trust desired is from the [real]world down into and over the nodes, this one isn't really useful. You then still have to use your key to form [real]world WOT among operators. Tying nodes to some [nym] identities is the first part... in a way, making sybil harder. Then users opting to route paths through tor via trust metrics need to configure their client with whichever various trusted wot/root keys they like or subscribe to, which then uses them to score fingerprints for pathing. Doing this with them is second part. Degree of freedom from some crossing of trusted key people is probably sufficient to score things. ___ tor-relays mailing list tor-relays@lists.torproject.org https://lists.torproject.org/cgi-bin/mailman/listinfo/tor-relays

For example, I might be inclined to route my traffic only over nodes run by those posting to this list, as opposed to also over the thousands of nodes that are nothing to me but an IP address.

[tor-relays] Node Operators Web Of Trust
Is it not time to establish a node operator web of trust? Look at all the nodes out there with or without 'contact' info, do you really know who runs them? Have you talked with them? What are their motivations? Are they your friends? Do you know where they work, such as you see them every day stocking grocery store, or in some building with a badge on it? Does their story jive? Are they active in the community/spaces we are? Etc. This is huge potential problem. NOWoT participation is optional, it is of course infiltratable, and what it proves may be arguable, but it seems a necessary thing to try as a test of that and to develop a good model. Many operators know each other in person. And the node density per geographic region supports getting out to meet operators even if only for the sole purpose of attesting 'I met this blob of flesh who proved ownership of node[s] x'. That's a big start, even against the sybil agents they'd surely send out to meet you. Many know exactly who the other is in the active community such that they can attest at that level. And so on down the line of different classes of trust that may be developed and asserted over each claimed operator. Assuming a NOWoT that actually says something can be established, is traffic then routable by the user over nodes via trust metrics in addition to the usual metrics and randomness? WoT's are an ancient subject... now what are the possibilities and issues when asserting them over physical nodes, not just over virtual nodes such as an email address found in your pubkey? And what about identities that exist only anonymously yet can prove control over various unique resources? If such WoT's cannot be proven to have non-value, then it seems worth doing. This doesn't just apply to Tor, but to any node based system. ___ tor-relays mailing list tor-relays@lists.torproject.org https://lists.torproject.org/cgi-bin/mailman/listinfo/tor-relays

Re: [tor-relays] Node Operators Web Of Trust
How does one establish trust online though? Trust is a very delicate thing. A system such as this simply inherently has these challenges. Pretty sure that is why the tor browser for example always uses https. Indeed, both the centralised and decentralised systems that are currently in place have major issues. Within centralised systems like the Certificate Authority system we see corruption (have you seen their fees) and we must trust them to actually verify identities and to remain secure, something at least a few CAs have proven that they can't do. Then we also have to trust our vendors to provide default lists of CAs to trust that are in fact worth of our trust. Within decentralised systems like PGP we have to worry about the network effect, and making sure that people understand what they are actually doing, again we worry about whether or not we can trust our friends, and whether or not we can trust their friends. Trust is probably one of the hardest problems facing folks using the Internet. With that in mind, he does raise a valid point. Are there any plans to move to a more decentralised model for the directory authorities? Are their any plans to move the power to blacklist nodes out of the hands of the Tor Project and into the hands of its users somehow. I'm not exactly sure how either of those would be accomplished, but I'm sure there is a clever solution somewhere.

This is pretty interesting point, but then i'm personally not really interested in having any control over the actual blacklist. I'd feel plenty comfortable with just insight into what is blacklisted, for what reason and if possible some evidence to support this reason. Giving control to the people isn't always a good thing either as even in TOR circles there'd be people that can't deal with having power on any level. Transparency is probably the word I was looking for to use. I didn't fill in contact information on my fresh tor relay simply because the app I use doesn't allow me to. (my tor relay runs on an Ouya, therefore android) Regardless of the absence of contact information the reason I run the relay are in line with the reasons why TOR exists. 2014-11-07 22:35 GMT+01:00 Derric Atzrott datzr...@alizeepathology.com: How does one establish trust online though?
