Title : Password-Authenticated Diffie-Hellman Exchange (PAK)
Author(s) : A. Brusilovsky, et al.
Filename : draft-brusilovsky-pak-05.txt
Pages : 8
Date : 2007-7-8
This document proposes to add mutual authentication, based on
human-memorizable password, to the basic unauthenticated Diffie-Hellman
key exchange. The proposed algorithm is called Password-authenticated
Key exchange (PAK). PAK allows two parties to authenticate themselves
while performing the Diffie-Hellman exchange.
The protocol is secure against all passive and active attacks.
In particular, it does not allow either type of attackers to obtain any
information that would enable an off-line dictionary attack on the
password. The use of Diffie-Hellman exchange ensures Forward Secrecy.

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.
