With the fast evolution of digital data exchange, security information becomes much important in data storage and transmission. Due to the increasing use of images in industrial process, it is essential to protect the confidential image data from unauthorized access. In this paper, we analyze the Advanced Encryption Standard (AES), and we add a key stream generator (A5/1, W7) to AES to ensure i...

This document supports the encryption algorithm E2 submitted as a candidate of Advanced Encryption Standard (AES) established by the National Institute of Standards and Technology (NIST). If you have any questions or comments, please send them to

Evaluation of the Advanced Encryption Standard (AES) algorithm in FPGA is proposed here. This Evaluation is compared with other works to show the efficiency. Here we are concerned about two major purposes. The first is to define some of the terms and concepts behind basic cryptographic methods, and to offer a way to compare the myriad cryptographic schemes in use today. The second is to provide...

The Advanced Encryption Standard (AES) was specified in 2001 by the National Institute of Standards and Technology [1]. The purpose is to provide a standard algorithm for encryption, strong enough to keep U.S. government documents secure for at least the next 20 years. Now AES will largely replace triple-DES for government use, and will likely become widely adopted for a variety of encryption n...
