A Compact S-Box Design for SMS4 Block Cipher - IACR

Webb1.2 SM4 SM4 is a Chinese block cipher standard with 128-bit key and 128-bit input/output block. Encryption and decryption takes 32 rounds, each of which generates a new block … The Rijndael S-box was specifically designed to be resistant to linear and differential cryptanalysis. This was done by minimizing the correlation between linear transformations of input/output bits, and at the same time minimizing the difference propagation probability. The Rijndael S-box can be replaced in the … Visa mer The Rijndael S-box is a substitution box (lookup table) used in the Rijndael cipher, on which the Advanced Encryption Standard (AES) cryptographic algorithm is based. Visa mer The inverse S-box is simply the S-box run in reverse. For example, the inverse S-box of b816 is 9a16. It is calculated by first calculating the … Visa mer The S-box maps an 8-bit input, c, to an 8-bit output, s = S(c). Both the input and output are interpreted as polynomials over GF(2). … Visa mer The following C code calculates the S-box: Visa mer photography on the net lens sample archive
