The DNS PRIVate Exchange (DPRIVE) Working Group develops mechanisms to
provide confidentiality to DNS transactions, to address concerns
surrounding pervasive monitoring (RFC 7258).

The set of DNS requests that an individual makes can provide an
attacker with a large amount of information about that individual.
DPRIVE aims to deprive the attacker of this information. (The IETF
defines pervasive monitoring as an attack [RFC7258])

The primary focus of this Working Group is to develop mechanisms that
provide confidentiality between DNS Clients and Iterative Resolvers,
but it may also later consider mechanisms that provide confidentiality
between Iterative Resolvers and Authoritative Servers, or provide
end-to-end confidentiality of DNS transactions. Some of the results of
this working group may be experimental.

DPRIVE is chartered to work on mechanisms that add confidentiality to
the DNS. While it may be tempting to solve other DNS issues while
adding confidentiality, DPRIVE is not the working group to do this.
DPRIVE will not work on any integrity-only mechanisms.

Examples of the sorts of risks that DPRIVE will address can be found
in [draft-bortzmeyer-dnsop-dns-privacy], and include both passive
wiretapping and more active attacks, such as MITM attacks. DPRIVE will
address risks to end users’ privacy (for example, which websites an
end user is accessing).

Some of the main design goals (in no particular order) are:

- Provide confidentiality to DNS transactions (for the querier).

- Maintain backwards compatibility with legacy DNS implementations.

- Require minimal application-level changes.

- Require minimal additional configuration or effort from applications or users
