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 $\operatorname {GF} (2)$. WebThe matrix has to go to the left of the column so that matrix multiplication is defined. In this answer, I'll show the steps for multiplying the first column of the state with the first row of the fixed MixColumns matrix: (d4 ⋅ 02) + (bf ⋅ 03) + (5d ⋅ 01) + (30 ⋅ 01) = 04 sharda in englishWebDec 4, 2024 · For encryption, I only do a matrix multiplication of each hex of ascii I get from files.
