Explanation:
Detailed explanation-1: -Explanation: The matrices are called states. Explanation: In AES the 4×4 bytes matrix key is transformed into a keys of size 44 bytes.
Detailed explanation-2: -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.
Detailed explanation-3: -The AES Encryption algorithm (also known as the Rijndael algorithm) is a symmetric block cipher algorithm with a block/chunk size of 128 bits. It converts these individual blocks using keys of 128, 192, and 256 bits. Once it encrypts these blocks, it joins them together to form the ciphertext.
