Abstract

The advanced encryption standard (AES) is currently recognized as one of the most popular cryptographic algorithms. The substitution block, better known as S-Box, is the key element in this encryption algorithm. Various schemes have been put forward in the past to construct S- Box, most of which are concerned with the reduction in the chip area and increasing the speed of operations. This paper presents realization of an area efficient S-Box structure based on Galois field arithmetic that is also optimized for speed. In the paper, we discuss implementation details of our proposed S-Box using very high speed integrated circuit (VHSIC) hardware description language (VHDL) and its comparison with the existing S-Box architectures. The results on simulation validate the merits of the suggested research. The S-Box architecture herein has been realized in Xilinx.
