信息安全加密算法第7部分:可调整分组密码

[中文适用范围]： 本文档指定了可调整的分组密码。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 位排列系列。这些原语是通用工具，可以用作构建加密方案（如加密、消息认证码、认证加密等）的构建块。 [外文原描述]： 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.
