WebApr 10, 2024 · SM4 symmetric encryption operation consists of 32 round functions, and the entire encryption process originally required 36 32-bit registers. With our tricks, only 4 32-bit registers are used in the entire process. Then we optimized the implementation of …
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.
