Extensions to the Domain Name System (DNS) can provide data origin and transaction integrity and authentication to security aware resolvers and applications through the use of cryptographic digital signatures. However, these security extensions do not provide authentication at the transaction or message level. This document describes a message authentication scheme (called SIG(0)) that provides message level authentication and integrity checking by means of a meta-RR in the additional section of a DNS message.
