With DNSSEC, we get the knowledge that a .LY domain probably has TLS keys controlled by Libya, and, if we're very savvy, the knowledge that .IO keys are controlled by GCHQ. We don't get consequences (you can't take .IO away from its owners, and Google simply isn't going to move from .COM, which is controlled by NSA), and we only get pinning's security with many more years of effort that haven't yet been sunk into DANE.
I remain impressed that people who were up in arms about the Snowden revelations, or, just yesterday, about NSA stockpiling zero-days, could casually rationalize the largest transfer of control over the Internet to governments in the whole history of the net.
And not all ccTLDs are controlled by that country's authorities, they are normally delegated to other organizations which in some cases may not even be under their jurisdiction.
There's also no movement of control to "governments". The entity that controls the TLD has authority over DNS, today, and the one with authority over DNS are in full control over DLV TLS certificates, today. Any pinning and transparency checks would work unimpeded in a DNSSEC world.
DNSSEC just makes it much harder to improperly get an TLS certificate. Today you just need to annouce their AS for a while, or cache spoof any of the hundreds of CAs. No CA has ever been dropped for signing a certificate by the rules. The only reason we don't see that more is because it's apparently even easier to bribe or force a CA to give them out. NSA certainly doesn't need to attack anything to get certificates issued, today.
I agree that governments control the DNS today.
The problem is that DNS does not in turn control Internet cryptography, and DNSSEC's primary use case is to change that.
That's a strange thing to say. DNS is pretty much the only thing that controls Internet cryptography. The number of non-domain validated certificates is vanishingly small.
Do I understand this correctly?
If there is a blacklist in place, absolutely each and every one of the hundreds of CAs need to adhere to it. One mistake or one exception and I could still get a misissued certificate just as easily as ten years ago.
Google can probably get it revoked very quickly, but we all know how well that works in practice. The only saving grace for the CA system is key pinning, and that's the only reason all those corrupt and/or incompentent CAs were exposed lately. But key pinning is not enough in itself. It is complementary to your certificate validation path(s).
I remain impressed that people who were at best ambivalent about the NSA and Snowden revelations, and other US Gov misdeeds, would use the fear of government control as their primary argument against DNSSEC.
Those folks are right about DNSSEC, of course. Their hemming and hawing about the NSA, Snowden, and the US government, I think history will judge harshly.
Is this me? I was, and am still, quite concerned about many of Snowden's revelations. I'm not as concerned about "passive" NSA vuln research as e.g. EFF are, although active sabotage of standards and deployed infrastructure has got to stop. I don't intend in this thread to rationalize anything, only to find out more about DNSSEC. For instance, why couldn't DNSSEC be used in addition to other methods such as TLS and DNSCrypt? I appreciate your insight in this area, but it's not clear that DDOS amplification (which, if it could be avoided by anyone, could be avoided by CF with their long experience in packet dropping) is enough of an issue to prevent even trying something like this.
ISTM this could at least be a transparency win, for average users. If trust went by TLD, we'd know that e.g. using "bit.ly" required trusting the Libyan domain admins. With CAs now, we just get a pile of CAs pre-installed with our OS or browser, and a bit of knowledgeable clicking is required in order to determine which CAs are trusted for any particular transaction. [EDIT: and in a sense, we are still trusting the Libyan domain admins.]
Whether one views the combination of CAs and TLD registrars that we have now as "defense in depth" or "more links in a chain" sort of depends on your threat model. Personally I'm more worried about identity thieves than oppressive governments, but others might have different concerns.
This may not offset the other problems you've identified.
