| TITLE | Design of a 128-Bit Advanced Encryption Standard and Optimization of the S-Box |
|---|---|
| ABSTRACT | The Advanced Encryption Standard (AES) is a widely adopted symmetric key cryptographic algorithm used for securing data in modern communication systems due to its robustness and efficiency. This work presents an optimized implementation of AES-128, focusing on both encryption and decryption architectures. In the proposed design, the conventional lookup table (LUT)-based Substitution Box (S-Box) is replaced with a Galois Field (GF) arithmetic-based S-Box, where substitution is performed using multiplicative inversion in GF(2⁸) followed by an affine transformation. This approach significantly reduces memory requirements and enhances hardware efficiency by eliminating the need for large precomputed tables. Furthermore, an optimized decryption architecture is developed to ensure correct inverse transformations while minimizing latency and resource utilization. Experimental results demonstrate improved area utilization and reduced hardware complexity without compromising performance. The design is suitable for VLSI and embedded security applications. |
