This document discusses the design and implementation of the AES (Advanced Encryption Standard) algorithm using FPGA and ASIC, focusing on its area efficiency. The proposed hardware-based solution processes 128-bit data blocks for encryption and decryption while optimizing speed and power consumption. Performance evaluations indicate that the AES-128 bit core achieves a throughput of 2.84 Gbps with a power consumption of 10.21 mW.
