TSIG Last modified: Thursday, December 27, 2007
Short for Transaction Signature, TSIG is a computer networking protocol used by the Domain Name System (DNS) as a way to authenticate updates to a dynamic DNS database. The RFC 2845 specification specifically states that the TSIG protocol allows for transaction level authentication using shared secrets and one way hashing. It can be used to authenticate dynamic updates as coming from an approved client, or to authenticate responses as coming from an approved recursive name server.
