Design and Implementation of Advanced Encryption Standard Security Algorithm using FPGA

In this paper, two architectures have been proposed, one for AES Encryption 128-bit process, and the other for AES Decryption 128-bit process. Both architectures are based on an iterative structure and modifications such as merging transformation (SubByte and ShiftRow in Encryption process, and Inverse SubByte and Inverse ShiftRow in Decryption process), Look Up tables for decryption, generating keys, and optimization of each clock cycle to incorporate maximum number of operations to improve the throughput and reducing hardware resources. The design has been described by VHDL and simulated by using Xilinx ISE 9.2i.The architectures have been implemented on reconfigurable platforms FPGAs. Accomplishment when implemented on Xilinx_Virtex4 (device xc4vlx80, package 12ff1148) which confirms that the proposed architectures have minimum hardware resource, where only 9% of the chip resources are used for AES Encryption design with realizable operating clock frequency of 382.988MHz, and only 9% of the chip resources are used for AES Decryption design with realizable operating clock frequency of 382.988MHz.

VHDL Based Implementation of AES system using FPGA

This project is basically designed to implement an encryption and decryption unit based on Advanced Encryption standard on a single chip by using VHDL algorithm. The basic working contains the encryption of plain text using a keyword of 128 bits as a input. Both the inputs are EX-OR and converted into state matrix of 4*4.The encryption process consist of Shifting of rows, mixing of columns for 7 rounds. After this the resultant output is EX-OR with another Keyword. This results in Cipher text of 128 bits. During Decryption, the process get reversed. Data path and control unit are designed for both cipher and decipher block, after that respective data path and control unit are integrated using structural modeling style of VHDL. Xilinx_ISE_14.2 software is being used for the purpose of simulating and optimizing the synthesizable VHDL code. The working of the implemented algorithm is tested using VHDL test bench wave form of Xilinx ISE simulator and resource utilization is also presented for a targeted Spartan3e XC3s500e FPGA

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.

… 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.
