Re: Let's move on - Let's DNSCurve Re: DNSSEC is NOT secure end to end

OK, how do you do that if the ICANN root is baked into your broadband
router? How about a light switch?

Yes in theory I can reverse engineer the code. In practice this is not
practical. In theory the music industry could set up their own
alternative to iTunes, in practice they have no choice but to deal
with Apple.

Most cell phones ship with only a small number of SSL roots and the
end user has no ability to change them.


You can change the signing key, but distributing and embedding the
verification key is a whole different issue. The reason that VeriSign
can charge a premium for certs is because its verification roots are
the most widely embedded.

You may disagree with my arguments here, but you do not have the
standing to call them 'specious'.
