Excerpt
Introduction: The Secret Key Transaction Authentication for DNS (TSIG) [RFC2845] protocol was developed to provide a lightweight authentication and integrity of messages between two DNS entities, such as client and server or server and server. TSIG can be used to protect dynamic update messages, authenticate regular message or to off-load complicated DNSSEC [RFC2535] processing from a client to a server and still allow the client to be assured of the integrity of the answers.
