DNS Security Extensions (DNSSEC) is a proposed standard for securely authenticating information in the Domain Name System. DNSSEC validators check the digital signatures on DNS data. However, designing a validator worth the operational costs is a challenge. The authors examine several design options and discuss DNSSEC deployment's added cost to performance, using the Unbound caching validating resolver as an example.
