WebSM4 is a popular block cipher issued by the Office of State Commercial Cryptography Administration (OSCCA) of China. In this paper, we use the bitslicing technique that has been shown as a powerful strategy to achieve very fast software implementations of SM4. We investigate optimizations on multiple frontiers. WebFeb 19, 2024 · SM4 is a block cipher algorithm whose block size and key length are both 128 bits. It adopts an unbalanced Feistel structure and iterates its round function 32 times during the encryption phase, where X_i \in Z^ {32}_ {2}, i = 0, 1, \ldots , 35 represents a bit string of length 32 bits respectively. WebSM4 is a 32-round iterative unbalanced Feistel network with both block length and key length being 128-bit. The structures of encryption process and decryption process are similar except that the round keys are used in the reverse order. The encryption algorithm flow is illustrated in Figure 1.
