A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Host Identity Protocol Working Group of the IETF.
Title : Host Identity Protocol
Author(s) : R. Moskowitz, et al.
Filename : draft-ietf-hip-base-01.txt
Pages : 104
Date : 2004-10-27
This memo specifies the details of the Host Identity Protocol (HIP).
The overall description of protocol and the underlying architectural
thinking is available in the separate HIP architecture specification.
The Host Identity Protocol is used to establish a rapid
authentication between two hosts and to provide continuity of
communications between those hosts independent of the networking
layer.
The various forms of the Host Identity, Host Identity Tag (HIT) and
Local Scope Identifier (LSI), are covered in detail. It is described
how they are used to support authentication and the establishment of
keying material, which is then used by IPsec Encapsulated Security
payload (ESP) to establish a two-way secured communication channel
between the hosts. The basic state machine for HIP provides a HIP
compliant host with the resiliency to avoid many denial-of-service
(DoS)attacks. The basic HIP exchange for two public hosts shows the
actual packet flow. Other HIP exchanges, including those that work
across NATs are covered elsewhere.

In the body type:
"FILE /internet-drafts/draft-ietf-hip-base-01.txt".
NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
