چکیده

The Advanced Encryption Standard (AES), which implements the Rijndael cipher, is a symmetric block cipher that was developed as a result of a call by the United States National Institute of Standards and Technology in 1997 for a secure cryptosystem to replace the then standard Data Encryption Standard algorithm, which had become vulnerable to brute-force attacks. Among several proposals, the Rijndael cipher was chosen and was renamed AES in 2001. The cryptosystem is based on a strong mathematical background of field theory, the basics of which we describe in the following section. Next, we present the encryption algorithm, with a note that the decryption, as in all symmetric cryptosystems, uses the same key and the inverse transformations and multiplicative inverses of the polynomials used for encryption. The remainder of the paper discusses the real-life implementations of the algorithm and concluding remarks [2].

Hardware Implementation of Dynamic S-BOX to Use in AES Cryptosystem

One of the major cipher symmetric algorithms is AES. Its main feature is to use S-BOX step, which is the only non-linear part of this standard possessing fixed structure. During the previous studies, it was shown that AES standard security was increased by changing the design concepts of S-BOX and production of dynamic S-BOX. In this paper, a change of AES standard security is studied by produc...
