The DNSSEC mechanism of authentication of communication between hosts is fulfilled by means of [[TSIG]]. More specifically, the [[TSIG]] is used to securely authenticate the transactions between the name servers and the resolver. The DNSSEC mechanism of establishing authenticity and data integrity is achieved by means of: new RRs, signing a single zone, building a trust chain and by means of [[key rollers]] or [[key exchange]]. | The DNSSEC mechanism of authentication of communication between hosts is fulfilled by means of [[TSIG]].
