          Definition and Use of DNSSEC Negative Trust Anchors
               draft-ietf-dnsop-negative-trust-anchors-00

Abstract

   DNS Security Extensions (DNSSEC) is now entering widespread
   deployment.  However, domain signing tools and processes are not yet
   as mature and reliable as those for non-DNSSEC-related domain
   administration tools and processes.  Negative Trust Anchors
   (described in this document) can be used to mitigate DNSSEC
   validation failures.
