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.
