Abstract
This paper presents the results of our study in the energy efficient AES encryption using S-box based on Galois-field (GF) aiming for a wireless FPGA node. The mapped composite-field GF(24)2 has been applied to compute S-box. In order to implement the energy efficient AES on FPGA for wireless sensor networks application, the several architectures such as pipelining and parallelism AES have been compared and analyzed. The low power design technique named gating is also applied to enable the necessary logics. By using this technique, we can gain the power saving about 19 percentages. In addition, the AES based on GF(24)2 gives the throughput per milli-Watts better than the AES based on LUT about 33 percentages. From the results, the AES based on GF (24)2 has been therefore chosen to build on a wireless reconfigurable node instead of using a basic structure; LUT in FPGA.
