AES ENCRYPTION AND DECRYPTION

AES means Advanced encryption standard. AES have four process.AES operation is secured our information.

    1.Subbytes
    2.Shiftrows
    3.Mixedcolumn
    4.Addroundkey

We going to implement 128 bit of AES encryption and decryption. after finishing four process called one round or one loop. we design 128 bit AES. So, we take 10 rounds based on bit sizes.
