FPGA implementation of AES encryption and decryption

… 2009. INCACEC 2009 …, 2009

Advanced Encryption Standard (AES), a Federal Information Processing Standard (FIPS), is an approved cryptographic algorithm that can be used to protect electronic data. The AES can be programmed in software or built with pure hardware. However Field Programmable Gate Arrays (FPGAs) offer a quicker and more customizable solution. This paper presents the AES algorithm with regard to FPGA and the Very High Speed Integrated Circuit Hardware Description language (VHDL). ModelSim SE PLUS 5.7g software is used for simulation and optimization of the synthesizable VHDL code. Synthesizing and implementation (i.e. Translate, Map and Place and Route) of the code is carried out on Xilinx -Project Navigator, ISE 8.2i suite. All the transformations of both Encryption and Decryption are simulated using an iterative design approach in order to minimize the hardware consumption. Xilinx XC3S400 device of Spartan Family is used for hardware evaluation. This paper proposes a method to integrate the AES encrypter and the AES decrypter. This method can make it a very low-complexity architecture, especially in saving the hardware resource in implementing the AES (Inv) Sub Bytes module and (Inv) Mix columns module etc. Most designed modules can be used for both AES encryption and decryption. Besides, the architecture can still deliver a high data rate in both encryption/decryption operations. The proposed architecture is suited for hardware-critical applications, such as smart card, PDA, and mobile phone, etc.

FPGA IMPLEMENTATION OF ENCRYPTION AND DECRYPTION ALGORITHM BASED ON AES

This paper presents FPGA based implementation scheme of advance encryption standard AES-128 (with 128 bit Key) encryption and decryption algorithm. The advance encryption standard is a symmetric block cipher that is intended to replace DES as the approved standard for a wide range of application. The 128-bit plain text and 128-bit initial key, as well as the 128-bit output of cipher text, are all divided into four 32-bit consecutive units respectively controlled by the clock. The algorithm is designed and synthesized using Xilinx ISE 13.4 simulated by ISim 0.87xd then implemented on Xilinx FPGA devise XC3S500E the result is verified using standard test vectors.

Comparison of various strategies of implementation of the algorithm of encryption AES on FPGA

2006 IEEE International Symposium on Industrial Electronics, 2006

The data security is a significant subject for which various solutions algorithms were proposed. In 2001, Advanced Encryption System (AES) was accepted like a standard FIPS. AES is a symmetrical algorithm of encoding intended to replace DES which had already shown certain faults of safety in the data protection. Since then, of many achievements on hardware and software were proposed by combining various architectures. The throughput reached go from 20 Mbps to 70 Gbps according to technology and architecture used. This article presents an architecture which can be implemented on the FPGA Xilinx XC2V6000, by applying dynamic reconfiguration and reaching a speed of execution of 43 Gbps. This architecture employs only 2xxx CLB' S allowing a considerable economy of the resources.
