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

Mail origin authentication

Secure routing information repository?
