Title : Symmetric-key Based IPv6 Addresses

A cryptographically generated address (CGA) is an IPv6 address
generated by applying a hash function over the public key of a node
and some additional parameters. CGA ownership can be asserted only
by the node claiming the address, but is readily verifiable using the
public-key of that node by any other entity. Such address
authorization is also plausible using symmetric keys, where a node
generating the self-identifying address shares a key with the
verifier or its agent. This document specifies symmetric-key based
address (SBA) generation. The infrastructure support comes with
several advantages including proxy-mode operation; the symmetric key
usage results in efficient operation; and finally the use of keyed
hashing provides security advantages over CGAs.

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.
