[dnssd] Fwd: New Version Notification for draft-pusateri-dnsop-private-subdomains-00.txt

[Tom Pusateri <[e-mail]>]

During the re-charter discussion last summer in Montréal, I presented some observations about service discovery to help focus our future work.

1. We should transition from using mDNS to using unicast DNS when possible for privacy, performance, and resource conservation. When we do use multicast, it should be for initial discovery but not for data transfer.
2. Some services are personal. Some services are meant to be openly shared, some are private.
3. Some services are location dependent but not necessarily network attachment dependent. Think on campus but attached cellular.

The Update proxy that I submitted on 12 Feb is meant to stimulate a discussion for #1.

This drafty draft below is meant for discussion on #2. It describes a method of creating personal subdomains for sharing private services. Unlike some of the other privacy solutions being discussed, it is not intended for use over mDNS but only over unicast DNS. Since it is still a work in progress, it would benefit from some other collaborators and so if you read the draft and have some contributions to make, I would love to work together. Protecting service discovery is not a security solution on its own. It’s just one more piece of the puzzle to not leak private information.

Thanks and see you in Prague.

Tom

> Abstract:
>   This document describes a method of providing private DNS subdomains
>   such that each subdomain can be shared among multiple devices of a
>   single owner or group.  A private subdomain can be used for sharing
>   personal services while increasing privacy and limiting knowledge of
>   scarce resources.
