Q1.) Advanced Encryption Standard (AES) is a symmetric block cipher encryption that receives 128-bit size for each block and the size of key is 128, 192, and 256 bits. AES procedure involves some encryption rounds, which are determined by the cipher key size. The mentioned standard uses 10 rounds in AES-128, 12 rounds in AES-192, and 14 rounds in AES-256. Through encryption, every round is collected as a set of four main transformations. Figure 2 displays the main construction of the encryption in AES method. Each round covers four main transformations: SubByte, Shift Row, Mix Column, and Add Round Key.
