Title : LHIP Lightweight Authentication Extension for HIP
Author(s) : T. Heer
Filename : draft-heer-hip-lhip-00.txt
Pages : 45
Date : 2007-3-2
This document specifies the Lightweight authentication extension for
the Host Identifier Protocol (LHIP). The goal of LHIP is to reduce
the computational requirements of the Host Identifier Protocol (HIP),
thus, making its benefits, such as end-host mobility and multihoming,
accessible to CPU-restricted devices. LHIP reduces the computational cost of establishing, updating, and closing a HIP association by
providing an alternative way of signing and verifying HIP control
packets which is based on computationally inexpensive hash function
computations and hash chains. However, LHIP does not provide nor
does it aim at providing the same level of security as HIP does.
Especially, host authentication and payload encryption are not
possible. The LHIP extensions in this draft specify also mechanisms
for dynamic transitioning between lightweight and full HIP
associations on the fly.

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
