+1 We are very much on-board with the direction of this discussion, DNS lookup is the way we would lean given vendor support for DNS/ENUM vs. HTTP. I think there is also something to say for keeping a limited scope of DNS as a good thing, vs. the infinite extensibility of HTTP. Does the current draft charter include this general direction as in scope?

For example, when receiving a request from 'alice@foo.com' we could do a DNS lookup for '_cid.foo.com' or some such pre-defined naming scheme, to get the caller-id cert for 'foo.com'; or the RR for that DNS key could redirect us to somewhere else if need be. Or we could do an HTTP automatically for 'http://foo.com/cid', or even 'http://foo.com/cid/ldkjhlashl' where the last part is a hash of the username. > > Or if we want the signer to be able to specify different certs for different requests, we support including a small token that gets appended to the automatic DNS or URL scheme for cert retrieval. For example up to a 16-character token. The only reason to limit its size would be to possibly get it (along with the signature and other info) through PSTN links in a UUI or whatever, but if we don't care about that for the email-style name cases then we could continue using the Identity-Info header for that case. I recognize the nice property of Identity-Info giving the URL was the cert could be hosted somewhere else, separate from the From's domain. > > >> So again, to the question of how golden the root is, I at least pictured a >> national-level root for telephone number identity that would, if at all >> possible, eliminate the problem of multiple trust anchors issuing >> credentials for the same identity. > > Right so I think we're all on the same page for that then. :) > > >> Just like the same cert could be >> included by CID or referred to by HTTP, though, I imagine there could be >> more than one protocol for getting at those credentials. > > I'm ok with specifying multiple protocols for accessing it - I mean that'll probably happen anyway (my company's products support half a dozen different ones to access routing DBs, for example) - but I think there needs to be one that's mandatory-to-implement, to get interoperability. Even if we believe *only* carriers will be the ones to query for STIR certs, many carriers buy products from multiple vendors they need to interoperate. Even the ones that buy the SIP-based equipment from only one vendor, often get the databases (or access to a separately managed one) from someone else. > > >> As for whether or not we need NPAC-style databases - agreed that here we >> don't need most of the data that's in them (like, LRNs aren't obviously >> material to solving our problem), but the authority structures they >> reflect are absolutely integral to this.
