Cryptography is related to the system of converting ordinary undeniable text into unintelligible textual content and vice versa. Symmetric key algorithms namely Advanced Encryption Standard (AES), and Data Encryption Standard use the equal key for encryption and decryption. It is lots quicker, easy to put into effect, and requires much less processing strength. Because of Side Channel attacks where attackers' Key leaked during the encryption process such as power consumption, or at execution time. The feature Key extraction will be from the photo pixel so one can accept the encryption and decryption of AES without the use of the schematic key to enhance the security of the data when Key leakage from insider threats or from improper key storage.

AES (Advanced Encryption Standard), LUT (Look up table),Sub bytes, shift rows,mix column, add round key.
