WebbThe SM4 blockcipher with a 128-bit key in CBC, ECB, CFB, OFB and CTR modes respectively. NOTES Developers should be aware of the negative performance … 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…
