To design a Substitutin BOX (S-BOX) using both encryption and decryption. From that, the proposed system can achieve a higher throughput and higher energy efficiency. The S-BOX is designed by using Advanced Encryption Standard (AES). The AES is a symmetric key standard for encryption and decryption of blocks of data. In encryption, the AES accepts a plaintext input, which is limited to 128 bits, and a key that can be specified to be 128 bits to generate the cipher text. In decryption, the cipher text is converted to original one.
