Abstract

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.
