Title : Privacy Extensions for DNS-SD
Authors : Christian Huitema

Filename : draft-ietf-dnssd-privacy-04.txt

Abstract:
DNS-SD (DNS Service Discovery) normally discloses information about
both the devices offering services and the devices requesting
services. This information includes host names, network parameters,
and possibly a further description of the corresponding service
instance. Especially when mobile devices engage in DNS Service
Discovery over Multicast DNS at a public hotspot, a serious privacy
problem arises.

We propose to solve this problem by a two-stage approach. In the
first stage, hosts discover Private Discovery Service Instances via
DNS-SD using special formats to protect their privacy. These service
instances correspond to Private Discovery Servers running on peers.
In the second stage, hosts directly query these Private Discovery
Servers via DNS-SD over TLS. A pairwise shared secret necessary to
establish these connections is only known to hosts authorized by a
pairing system.
