After explaining the relation between Rijndael and AES, we describe the features of Rijndael. This is followed by the description of the Rijndael cipher structure, the round transformation and its steps, and the key schedule.
Rijndael and Aes
On October 2, 2000, the US federal agency National Institute of Standards and Technology (NIST) officially announced that Rijndael would become the Advanced Encryption Standard (AES). NIST chose Rijndael from a set of 15 candidates after a 3-year public and fully open selection and evaluation process. The choice was motivated in an excellent 116-page report in which they summarize all contributions and motivate the choice [4].
Both Rijndael and AES are block ciphers that provide a mapping from plaintext blocks to ciphertext blocks and vice versa under a cipher key. Rijndael supports all combinations of block lengths and keylengths that are a multiple of 32 bits with a minimum of 128 bits and a maximum of 256 bits. The Rijndael reference...
