WebbSM4 is a symmetric encryption algorithm, specifically a blockcipher, designed for data encryption. This document does not aim to introduce a new algorithm, but to provide a clear and open description of the SM4 algorithm in English, and also to serve as a stable reference for IETF documents that utilize this algorithm. Webb9 maj 2024 · SM4为分组对称密码算法，明文、密文以及密钥长度均为128bits。SM4算法主要包括加解密算法和密钥扩展算法，采用32轮非线性迭代的数学结构，其中算法中每一次迭代运算为一轮非线性变换。主要操作包括异或、合成置换、非线性迭代、反序变换、循环移位以及S盒变换等。
