Information security — Message authentication codes (MACs) — Part 2: Mechanisms using a dedicated hash-function

Sécurité de l'information — Codes d'authentication de message (MAC) — Partie 2: Mécanismes utilisant une fonction de hachage dédiée

Abstract / scope

This document specifies MAC algorithms that use a secret key and a hash-function (or its round-function or sponge function) to calculate an m-bit MAC. These mechanisms can be used as data integrity mechanisms to verify that data has not been altered in an unauthorized manner.

NOTE       A general framework for the provision of integrity services is specified in ISO/IEC 10181‑6.
