== DNSSECの用途 ==
NANOG51 の tutorial から

What will DNSSEC be used for?
 •  Protecting applications against DNS spoofing attacks
   •  Recursive name servers will perform DNSSEC validation and
       throw away bad data before it reaches downstream clients
   •  Eventually some stub resolvers and even applications may do
       their own DNSSEC validation

 •  Opening up DNS as a secure repository for various kinds of data
{{{
Web site authentication and privacy
     •  Self-signed X.509 certificates authenticated by DNSSEC
Mail origin authentication
SSH host key authentication
Publication mechanism for other public keys?
Secure routing information repository?
The sky’s the limit if data from the DNS has a higher level of trust than currently
