Rijndael is an SPN (Substitution Permutation Network) structure block cipher, which was recently selected as the AES (Advanced Encryption Standard) algorithm. In this paper, we describe some algebraic properties of the basic functions used in Rijndael, and introduce consistent differential patterns of this cipher. We then describe how these properties can be applied to the cryptanalysis of this cipher.
