On Partial Linearization of Byte Substitution Transformation of Rijndael-The AES
Abstract: Rijndael-The AES is 128-bit block cipher based on an elegant algebraic structure over F2. This cipher employs a simple approach to its substitution, permutation (SP) operations. We take a close look at its internals; the byte substitution transformation function is the only non-linear function in Rijndael The AES. This transformation comprises of two steps operating on each byte. Here...
متن کاملA Novel Byte-Substitution Architecture for the AES Cryptosystem
The performance of Advanced Encryption Standard (AES) mainly depends on speed, area and power. The S-box represents an important factor that affects the performance of AES on each of these factors. A number of techniques have been presented in the literature, which have attempted to improve the performance of the S-box byte-substitution. This paper proposes a new S-box architecture, defining it...
متن کاملRijndael: beyond the AES
In October 2001, after a 3-year evaluation process, NIST announced its decision to propose the Belgian algorithm Rijndael for the AES. In this paper, we discuss some of the work that has been done on Rijndael since its selection as the AES. We also outline briefly the design of a related cipher, called Anubis, and compare both designs.

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
