WebHow to find a modular inverse. A naive method of finding a modular inverse for A (mod C) is: step 1. Calculate A * B mod C for B values 0 through C-1. step 2. The modular inverse of A mod C is the B value that makes A * B mod C = 1. Note that the term B mod C can only have an integer value 0 through C-1, so testing larger values for B is redundant. WebFeb 24, 2016 · AES MixColumns is done by multiplying a $4 \times 4$ matrix and a column of the AES state (a vector). Addition and multiplication are done in $\operatorname {GF} (2^8)$. In the paper White-box AES, the authors use $32 \times 32$ matrix $\mathit {MC}$ times a $32 \times 1$ vector over $\operatorname {GF} (2)$. WebJun 24, 2024 · As mentioned in the rules above, matrix multiplication is only possible if the number of columns and rows of two matrices are the same.
