Abstract

This document describes a technique to generate valid DNSSEC answers on demand for non-existing names by claiming the name exists and returning a NSEC record for it. These answers require only one NSEC record and allow live-signing servers to minimize signing operations, packet size, disclosure of zone contents and required knowledge of the zone layout.
