Variations to the cryptographics algorithms AES and TWOFISH
Abstract
The cryptographic algorithms AES and Twofish guarantee a high diffusion by the use of fixed 4x4 MDS matrices. In this article variations to the algorithms AES and Twofish are made. They allow that the process of cipher - decipher come true with MDS matrices selected randomly from the set of all MDS matrices with the use of proposed algorithm. A new key schedule with a high diffusion is designed for the algorithm AES. Besides proposed algorithm generate new S - box that depends of the key.
