It has the property of aligning cryptographic authentication with the domain name hierarchy. Yes, you trust the hierarchy. You trust LE too, so what? We need to move away from any authority being able to authenticate anyone, and DNS naturally aligns with the goal.
You've been vocal for a long time against DNSSEC deployment too for no discernable reason.
Why are you against every single thing that tries to make DNS useful for securing anything?
DNSSEC creates more operational issues than it solves. It's easy to screw up, which means your domain completely stops resolving when that inevitably occurs. None of the FAANGs use it for their main web sites, so what does that tell you?
It can also be disabled at the whim of anyone operating a resolver, as was seen with Cloudflare during the .de TLD DNSSEC snafu back in May.
Do the words "no discernible reason" just mean something very different to you than they do to me? Because I've written somewhere in the vicinity of 100,000 words about the problems of DNSSEC over the last 20 years. My written DNSSEC critique predates HN itself.
This particular issue has nothing to do with "aligning authentication with the name hierarchy". The exact same thing that happened to EMudhra could happen to any TLD operator. The difference is that we have essentially no recourse when that happens, and far less ability to detect malfeasance.
Low TTLs aren’t incompatible with the ideal of using DNSSEC though? From what I can tell DS records typically have TTL of 1 day in the root domain.
What is a difference, versus DANE, is that TLS uses CT. Compromised TLDs happened recently but was found out through CT. A compromised TLD still kills the whole system for a time regardless.
I think DNSSEC still has some use in enforcing email TLS and for CAs.
Sorry, I'm a little confused as to how TTLs are at issue here? I don't think TTLs are a reason DNSSEC is problematic.
I meant that for a compromised TLD key, the DS record at root lasts for a day. So I didn’t follow how the compromise in a theoretical DANE-only world would be inherently long-lasting.
You said “no recourse,” which I took to mean no recourse even if known. I don’t follow that. The key/DS record at root can be changed. There may not be a “TLD death penalty,” but the key could be changed.
Now without CT it may be tougher to know about the compromise. For websites that don’t have the luxury of certificate pinning, a compromise of TLD kills the whole thing, at least for a time.
None of my arguments are that a compromised DNSSEC key would be inherently long-lasting?
The "recourse" issue is that after you resolve a DNSSEC misissuance, you cannot then murder the TLD operator that did that to you. But that's exactly what's about to happen with EMudhra.
