I-D ACTION:draft-krawczyk-keyed-md5-01.txt



A Revised Internet-Draft is available from the on-line Internet-Drafts 
directories.                                                               

       Title     : Keyed-MD5 for Message Authentication                    
       Author(s) : H. Krawczyk
       Filename  : draft-krawczyk-keyed-md5-01.txt
       Pages     : 5
       Date      : 11/22/1995

This document describes a keyed-MD5 mechanism for use as a message 
authentication code (MAC) (or, integrity check value -- ICV). It is mainly 
intended for integrity verification of information transmitted over open 
networks (e.g., Internet) between parties that share a common secret key. 
The proposed mechanism combines the (key-less) MD5 hash function [RFC-1321]
with a shared secret key.  The description of keyed-MD5 in this document is
independent of its use in any particular protocol. An analogous mechanism 
can be used in combination with other iterative hash functions, e.g., SHA.

Send a message to:  mailserv@ds.internic.net. In the body type: 
     "FILE /internet-drafts/draft-krawczyk-keyed-md5-01.txt".
							
NOTE: The mail server at ds.internic.net 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.
							
For questions, please mail to Internet-Drafts@cnri.reston.va.us.
							

Below is the data which will enable a MIME compliant mail reader 
implementation to automatically retrieve the ASCII version
of the Internet-Draft.

No recognizable part in multipart/alternative.
