Implementation and Design of AES S-Box on FPGA

The Advanced Encryption Standard can be programmed in software or built with pure hardware. However Field Programmable Gate Arrays (FPGAs) offer a quicker, more customizable solution. This research investigates the AES algorithm with regard to FPGA and the Very High Speed Integrated Circuit Hardware Description language (VHDL). Xilinx Design Suite 14.5 software is used for simulation and optimization of the synthesizable VHDL code. All the transformations of both Encryptions is simulated using an iterative design approach in order to minimize the hardware consumption. Virtex 6 Family devices are utilized for hardware evaluation. Advanced Encryption Standard (AES) is one of the most common symmetric encryption algorithms. The hardware complexity in AES is dominated by AES substitution box (S-box) which is considered as one of the most complicated and costly part of the system because it is the only non-linear structure. Theoretically, the design reduces the overall delay and efficiently for applications with high-speed performance. This approach is suitable for FPGA implementation in term of gate area. The hardware, total area and delay are presented.

2020

Cryptography is technique of preserving data from unwanted objects by transforming in the pattern that is unrecognizable by hackers while transmission. Encryption is the process where maximum part of informtion is scrambled like text-data, images, audio, and video so to make the data undcipherable, unseen untillthe proces is donef. The primary objective of cryptography is to protect information from non authoritzed hackers. The data decryption decryption is nothing but the receving of encrypted data which recreates the original information. At present cryptography is not limited to secure military document but known as one important method for policy of security cosidering any organization and recognized as standard for industry for giving secure data, access control, and financial agreement through electronic medium. The primary information that will be send or saved is known as plaintext, the which either a person or machine can read. Whereas the hidden information called cipher t...
