Design of a Masked S-Box for SM4 Based on Composite Field

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).
