Rijndael encryption algorithm is the grouping variable length block cipher. Packet length, key length for the bit 128,192,256. The assumption that an encrypted intermediate results for the state of State. State status is similar to the elements can be used as a matrix of bytes expressed as the number of rows for the matrix 4, the number of rows for the Nb, Nb equal to packet length divided by 32.
