The document compares the results of encrypting a plaintext using the original AES algorithm and a modified AES algorithm over 10 rounds. In each round, the key is scheduled and the plaintext is encrypted using substitution, shift row, mix column or modified mix column transformations. The output ciphertext after each round is different between the original and modified AES.
