A Review of AES and Visual Cryptographic techniques for added security

Abstract

With the increase in data theft, eavesdropping and hacking, a requisite for powerful data protection schemes arises. Many algorithms have been proposed in the past to enhance the speed and the security parameters of the cryptographic algorithms. The well-known algorithms that are currently in use are Advanced Encryption Standard (AES) for data and visual cryptography (VC) for the images. The scope of the project is to develop a highly secure encryption algorithm, by combining the AES and VC algorithms. The algorithms will be simulated in MATLAB and also, the architecture developed for the same will be downloaded on the Spartan 3E FPGA.
