AES-128/192/256 decryption algorithms processes cipher data blocks of 128 bits, generates plain data blocks of 128 bits using the same cipher keys of 128/192/256 bits in data encryption. Basic unit of AES algorithms operation is a two dimensional array of 16 bytes called states. Its mapping relation is illustrated in the following figure.
