Advanced Encryption Standard (AES), has received significant interest over the past decade due to its performance and security level. Many hardware implementations have been proposed. In most of the previous works sub bytes and inverse sub bytes are implemented using lookup table method and using same key at time in parallel process. This performed less time for complete this process. This paper proposes a high-throughput implementation of AES (Advanced Encryption Standard) supporting encryption and decryption with 128-bit cipher key.
