That's true, but the amount of trust you have to put in high-level DNSSEC
keys is relatively limited. DNSSEC is aware of zone cuts, and high-level
keys cannot authenticate domain names below a zone cut. The DNS also
caches a lot, so if an attacker tries to redirect part of the namespace
without obtaining the corresponding private keys, they will cause
suspicious validation failures at sites where the proper public keys were
It would be nice to have something better than DNSSEC, but at least it has
a safer structure than X.509.
