Advanced Encryption Standard (AES) is the current standard for secret key encryption. AES was created by the researchers to overcome the disadvantages of Data Encryption Standard (DES). The federal information processing standard 197 used a standardized version of the algorithm called Rijndael for the advanced encryption standard. The algorithm uses a combination of Exclusive-OR (XOR) operations, substitution with an S-box transformation, row and column rotations and mix-columns. All the transformations of encryption are simulated using an iterative design approach in order to minimize the hardware consumption.
