Hybrid VLSI Design for AES Cryptography with Pipelined Architecture

The Advanced Encryption Standard (AES) cryptography hybrid VLSI architecture presented in this study is optimized for the safe and effective encryption of both text and image data. A HASH algorithm block is incorporated into the architecture to improve key security and provide strong encryption for delicate applications. In order to overcome the inherent difficulties of implementing AES on Application-Specific Integrated Circuits (ASICs) and Field-Programmable Gate Arrays (FPGAs), a pipelined design is used to increase performance and throughput. SubBytes and MixColumns, two important AES components, are area-efficiently tuned, striking a balance between clock cycles and hardware resource usage. The hardware description of the 128-bit AES implementation is done using Verilog HDL, and MATLAB and Modelsim 6.4c are used for simulation. Using Xilinx tools, the design is verified and assessed, showcasing strong encryption and excellent performance. The design greatly improves key security by incorporating a HASH algorithm, which increases its resistance to cryptographic attacks. Additionally, the pipelined architecture guarantees increased throughput, allowing encryption jobs to be processed more quickly without sacrificing security. Applications requiring high security requirements and peak performance can benefit from this hybrid VLSI approach's effective trade-off between hardware complexity and encryption speed. The outcomes demonstrate how flexible the architecture is for many kinds of data, especially when it comes to protecting text and image data. This approach offers a strong blend of area efficiency, security, and performance, setting a standard for creating hardware-based cryptography systems.
