ISO/IEC 18033-7:20 22本文件规定了可调整分组密码。可调整分组密码是由秘密密钥值和公共调整值参数化的n位排列族。这种原语是通用工具，可以用作构建块来构建诸如加密、消息认证码、认证加密等的密码方案。 定义了总共五种不同的可调整分组密码。它们在表1中分类。

ISO/IEC 18033-7:2022 This document specifies tweakable block ciphers. A tweakable block cipher is a family of n-bit permutations parametrized by a secret key value and a public tweak value. Such primitives are generic tools that can be used as building blocks to construct cryptographic schemes such as encryption, Message Authentication Codes, authenticated encryption, etc.
A total of five different tweakable block ciphers are defined. They are categorized in Table 1.
