WebbCompute Structure The SM4 algorithm is a blockcipher, with block size of 128 bits and a key length of 128 bits. Both encryption and key expansion uses 32 rounds of a nonlinear key schedule per block. Each round … The SM4 cipher has a key size and a block size of 128 bits each. Encryption or decryption of one block of data is composed of 32 rounds. A non-linear key schedule is used to produce the round keys and the decryption uses the same round keys as for encryption, except that they are in reversed order. The length of encryption keys is 128 bits, represented as , in which is a 32-bit word. The round key… WebbSM4 adopts an unbalanced Feistel structure and iterates its round functions for 32 times in both encryption and key expansion algorithm.
