perhaps i am a bit slow. but could someone explain to me how trust in dns data transfers to trust in an http partner and other uses to which ssl is put?
If I can get secure answers to "www.bank.example IN CERT?" and "www.bank.example IN A?" then perhaps when I connect to www.bank.example:443 I can decide to trust the certificate presented by the server based on the trust anchor I extracted from the DNS, rather than whatever trust anchors were bundled with my browser.
That presumably would mean that the organisation responsible for bank.example could run their own CA and publish their own trust anchor, without having to buy that service from one of the traditional CA companies.
No doubt there is more to it than that. I don't know anything much about X.509.
