Hybrid Approach of Modified AES

Abstract

Advanced Encryption Standard is one of the most popular symmetric key encryption algorithms to many works, which have employed to implement modified AES. In this paper, the modification that has been proposed on AES algorithm that has been developed to decrease its time complexity on bulky data and increased security will be included using the image as input data. The modification proposed itself including alteration in the mix column and shift rows transformation of AES encryption algorithm, embedding confusion-diffusion. This work has been implemented on the most recent Xilinx Spartan FPGA.
