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

Joe,

You have argued that DNSSEC is not viable because it requires that everyone adopt IANA as the common root. I agree that under the current IANA management situation many folks may be uncomfortable with IANA as the root. However, in practice, the world has lived with IANA as the root for the non-secure version of DNS for a long time, so it's not clear that a singly-rooted DNSSEC is not viable based on this one concern. Moreover, DNSSEC is a form of PKI, an din ANY PKI, it is up to the relying parties to select the trust anchors they recognize. In a hierarchic system like DNS, the easiest approach is to adopt a single TA, the DNS root. But, it is still possible for a relying party to do more work and select multiple points as TAs. I would expect military organizations in various parts of the world to adopt a locally-managed TA store model for DNSSEC, to address this concern. However the vast majority of Internet users probably are best served by the single TA model.

As for DNSCurve, I agree with the comments that several others have made, i.e., it doe snot provide the fundamental security one wants in DNS, i.e., an ability to verify the integrity and authenticity of records as attested to by authoritative domains, din the face of caching.
