One method to protect the sensitive data is using symmetric-key block cypher before and after sending it over the network using same secret key. Advanced Encryption Standard (AES) is currently considered as best symmetric-key block cipher. With the block size of 128-bits and the key length starting from 128-bit up to 256-bits, AES has been proved to takes years to break. However, AES implementations in software also require more computations and time to encrypt and decrypt the data. This bottleneck not only reduces the overall system throughput but also increases the power consumption especially in the embedded system, where there are limited computations and resources. To improve the throughput and reduce the power consumption of the AES crypto system, in this work, we proposed a combined, low-cost and high-throughput AES encryption and decryption architecture supporting all key-lengths as specified in the FIPS197. The design was modeled in VHDL and successfully synthesized using Xilinx Virtex 5 FPGA Chip 5VSX50TF with maximum frequency of 105 MHz and the maximum throughput of 300 Mbps. date: 2014-11-14 type: Conference or Workshop Item type: PeerReviewed format: application/pdf language: en identifier: https://eprints.uet.vnu.edu.vn/eprints/id/eprint/431/1/icdv2014_submission_34_AES-FINAL.pdf identifier: Vu, Tien Luan and Quach, Van Quy and Bui, Duy Hieu and Tran, Xuan Tu (2014) A Low-Cost Implementation of Advance Encryption Standard.
