Description of Working Group:
The Host Identity Protocol (HIP) provides a method of
separating the end-point identifier and locator roles of
IP addresses. It introduces a new Host Identity (HI)
name space, based on public keys. The public keys are
typically, but not necessarily, self generated.
The specifications for the architecture and protocol
details for these mechanisms consist of:
draft-moskowitz-hip-arch-05.txt (at RFC editor) and
draft-moskowitz-hip-08.txt (soon -09.txt)
There are five publicly known, interoperating
implementations, some of which are open source.
Currently, the HIP base protocol works well with any pair
of co-operating end-hosts. However, to be more useful
and more widely deployable, HIP needs some support from
the existing infrastructure, including the DNS, and a new
piece of infrastructure, called the HIP rendezvous
server.
+-------------------------------------------------------+
| The purpose of this Working Group is to define the |
| minimal infrastructure elements that are needed for |
| HIP experimentation on a wide scale. |
+-------------------------------------------------------+
In particular, the objective of this working group is to
complete the base protocol specification, define one or
more DNS resource records for storing HIP related data,
to complete the existing work on basic mobility and
multi-homing, and produce Experimental RFCs for these.
Note that even though the specifications are chartered
for Experimental, it is understood that their quality and
security properties should match the standards track
requirements. The main purpose for producing
Experimental documents instead of standards track ones
are the unknown effects that the mechanisms may have on
applications and on the Internet in the large.
It is expected that there will be a roughly parallel,
though perhaps considerably broader, IRTF Research Group
that will include efforts both on developing the more
forward looking aspects of the HIP architecture and on
exploring the effects that HIP may have on the applications
and the Internet.
The following are charter items for the working group:
1) Complete the HIP base protocol specification.
Starting point: draft-moskowitz-hip-08.txt (or newer)
2) Complete the basic mobility and multi-homing support for HIP.
Starting point: draft-nikander-hip-mm-01.txt (or newer)
While this work partially overlaps the work in Mobile
IP and Multi6 Working Groups, it is very different in
the sense that is based on the Experimental HIP
specification, and cannot function without it.
3) Define one or more new DNS Resource Records for
storing HIP related data, such as Host Identifiers and
Host Identity Tags (HITs). This task explicitly
excludes the task of defining reverse DNS entries
based on HITs.
4) Define a basic HIP rendezvous mechanism.
A basic HIP rendezvous server allows mobile and
non-mobile HIP hosts to register their current IP
addresses at the server. Other hosts can then send
the initial I1 packets to the rendezvous server, which
forwards the packets to the HIP host's current address.
This task explicitly excludes solving more general
problems, such as the referral problem. Also excluded
is the problem of finding the right rendezvous server.
It is expected that the DNS records will be used for that.
The Working Group bases all the work on the HIP achitecture
specification (as defined above).
5) Complete the HIP Architecture specification
Starting point: draft-moskowitz-hip-arch-06.txt
