WebCompute 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 … 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… WebSM4 algorithm and AES algorithm have the same key length and the packet length is 128 bits, so it is more secure than 3DES algorithm.
