Sm4 block size

WebbMessage ID: [email protected] (mailing list archive)State: New, archived: Headers: show WebbSM4 also has a 128-bit block size, but only one key size, 128 bits. Even though its high-level structure differs completely from AES, the two share significant similarities in their sole nonlinear component, which is a single 8 8-bit “S-Box” substitution table in both cases.

Webb该模式使用在长度上为一个块且被分为几部分的移位寄存器。 例如，如果块大小为8 个字节，并且每次处理一个字节，则移位寄存器被分为 8 个部分。 如果密码文本中有一个位出错，则一个纯文本位出错，并且移位寄存器损坏。 这将导致接下来若干次递增的纯文本出错，直到出错位从移位寄存器中移出为止。 PKCS7：PKCS #7 填充字符串由一个字节序列 … Webb1 nov. 2024 · SM4 is a block cipher system with a block length of 128 bits (16 bytes). When we convert a genomic data file into a byte stream, the size of the input data is not necessarily a multiple of the block length, so we need to pad the data in the last block length of the input text. ffpdk.guizhou.chinatax.gov.cn https://theros.net
