Abstract—With computers, security is only a matter of software. The Internet has made computer security much more difficult than it used to be. In this paper, we introduce modified AES with S-boxes bank to be acted like rotor mechanism and dynamic key MDS matrix (SDK-AES). In this paper we try to make AES key dependent and resist the frequency attack. The SDK-AES algorithm is compared with AES and gives excellent results from the viewpoint of the security characteristics and the statistics of the ciphertext. Also, we apply the randomness tests to the SDK-AES algorithm and the results shown that the new design passes all tests which proven its security.
