Increasing need of data protection in computer networks led to the development of several cryptographic algorithms hence sending data securely over a transmission link is critically important in many applications. Hardware implementation of cryptographic algorithms are physically secure than software implementations since outside attackers cannot modify them. In order to achieve higher performance in today's heavily loaded communication networks, hardware implementation is a wise choice in terms of better speed and reliability. This paper presents the hardware implementation of Advanced Encryption Standard (AES) algorithm using Xilinx–virtex5 Field Programmable Gate Array (FPGA). In order to achieve higher speed and lesser area, Sub Byte operation, Inverse Sub Byte operation, Mix Column operation and Inverse Mix Column operations are designed as Look Up Tables (LUTs) and Read Only Memories (ROMs). This approach gives a throughput of 3.74Gbps utilizing only 1% of total slices in xc5vlx110t-3-ff1136 target device.

This document gives the hardware implementation of Mix Column step in AES encryption process. The AES encryption process consists of several transformation steps such as byte substitution, shift rows, mix column and addition of round key operation step. There are two aspects to perform mix column step in AES is presented. The total operation is coded with VERILOG, synthesized and simulated using Xilinx ISE 10.1.

The CPU cycles needed for symmetric encryption are fewer than for asymmetric encryption. So symmetric algorithms are faster than asymmetric algorithms. Advanced Encryption Standard (AES), Data Encryption Standard (DES), Triple DES, Rivest Cipher (RC2), Rivest Cipher (RC6), and Blowfish are some of the symmetric algorithms. Remote Secure Access is an asymmetric algorithm.The AES algorithm is very difficult to crack and is well suitable to security service applications. It is designed in a way that has better resistance against existing attacks. AES has more elegant mathematical formulas behind it and requires only one pass to encrypt data. It has very low memory requirements, so it is particularly well-suited to embedded applications such as smart cards.

Advanced Encryption Standard (AES) is one of the most secured encryption algorithm because of its robustness and complexity. Because of its complexity, AES has slow computation. This paper presents a Lightweight Advanced Encryption Standard (LAES) design by replacing the MixColumn transformation of the traditional AES with a 128-bit permutation to lessen its computational complexity. Implementation of hardware cryptographic encryption aims to find the best trade-off between throughput and resource utilization. The proposed design is synthesized on various Field Programmable Gate Array (FPGA) devices and achieves the maximum clock frequency of 480.50 MHz with the highest throughput of 6.15 Gbps when synthesized on Virtex 7 XC7VX690T. The results on other devices show a higher throughput, better performance efficiency, and lesser area utilization when compared to the existing AES hardware implementation.

This paper presents the implementation of the Advanced Encryption Standard algorithm on an 8-bit compact architecture. Encryption, key scheduling and decryption are implemented by small resources and extensive resource sharing. The architecture is perfectly suited for low cost applications which require moderately high data rates. Among the various cost effective and compact implementations already available, this architecture presents a novel design of the data path which has been modelled on 8-bit systolic architecture. The S-Box required for byte substitution has been implemented in BRAMS further reducing the consumed area. The design has been further embellished by a memory based controller which simplifies the control process and makes it viable for very effective hardware utilization. This produces one of the smallest implementations of the algorithm on FPGA with a reasonably high throughput. Considering the aforementioned, it minimizes area and power consumption, the basic factors of a low cost implementation. Comparisons drawn from FPGA implementation with other architectures have also been presented.
