WebbThe SM4 algorithm is a block cipher which has a block size of 128 bits and a key sizeof 128 bits. And each block and encryption key is spliced into four parts; each part has 32 bits. Encryption algorithm and decryption algorithm takes 32 rounds of nonlinear substitutions. WebbSM4 [ISO.IEC.18033-3.AMD2] is a cryptographic standard issued by the Organization of State Commercial Administration of China as an authorized block cipher for the use within China. Based on threshold implementations and operations in composite fields, ...
