The Euphrates Cipher
In the present paper we give a complete description for the proposed new variant of AES cipher with high level of security and coherent algebraic aspects that is called the EUPHRATES cipher. The EUPHRATES name has been derived from one of the two famous rivers in Iraq. It is a revision of the TIGRIS cipher which we have already proposed before. It works with block size 128-bits and three variable key lengths 128-bits, 192-bits and 256-bits similar to the AES standard. The EUPHRATES cipher uses the Galois Field GF (28) as the mathematical representation and provides a good insight to the block cipher design.
Keywords: Block Cipher, Advance Encryption Standard (AES), Substitution and Permutation Network (SPN), Maximum Distance Separable (MDS), Feistel Structure (FS).
