AES Round Function (one round)

Joan Daemen & Vincent Rijmen / NIST, 2001

The Advanced Encryption Standard (AES) iterates a round composed of SubBytes (S-box substitution), ShiftRows (permutation), MixColumns (GF(2⁸) linear mixing), and AddRoundKey (XOR with expanded key material). This canvas uses decorative Greek labels and staged motion to teach phase order; it never displays actual keys or ciphertext.
