Webb关键词: SM4分组密码算法, 差分密码分析, 线性密码分析, S盒 Abstract: SM4 Algorithm, short for SM4 Block Cipher Algorithm, was published in 2006 to promote the application of WAPI.It became a cryptography industrial standard (GM T 0002—2012) in March 2012 and a national standard (GB T 32907—2016) in August 2016. WebbSearch Tricks. Prefix searches with a type followed by a colon (e.g. fn:) to restrict the search to a given type. Accepted types are: fn, mod, struct, enum, trait, type, macro, and const. Search functions by type signature (e.g. vec -> usize or * -> vec) Search multiple things at once by splitting your query with comma (e.g. str,u8 or String,struct:Vec,test)

WebbThe size of the block and key of the SM4 cipher is 128 bits, which is similar to the AES128 cipher. The SM4 also implements 32 rounds of nonlinear iteration [ 8 ]. Initially, it was designed for protecting wireless networks, especially WLAN. WebbThe SM4 block cipher [14] fulfills a similar role to AES in the Chinese market and is the main block cipher recommended for use in China. It is also standardized with ISO [7]. …
Webb21 mars 2012 · The SM4 cipher has a key size and a block size of 128 bits each. [5] [6] 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.
