标准摘要
[中文适用范围]： 本文件指定了使用秘密密钥和哈希函数（或其轮函数或ponge函数）计算m位MAC的机制。这些机制可以用于数据完整性机制，以验证数据是否未以未经授权的方式更改。 [外文原描述]： 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.
