Abstract:
DNS queries and responses are visible to network elements on the path
between the DNS client and its server. These queries and responses
can contain privacy-sensitive information which is valuable to
protect. An active attacker can send bogus responses causing
misdirection of the subsequent connection.
To counter passive listening and active attacks, this document
proposes the use of Datagram Transport Layer Security (DTLS) for DNS,
to protect against passive listeners and certain active attacks. As
DNS needs to remain fast, this proposal also discusses mechanisms to
reduce DTLS round trips and reduce DTLS handshake size. The proposed
mechanism runs over the default DNS port and can also run over an
alternate port.
