ViewAug 20, 2020 · Rijndael became the Advanced Encryption Standard for the US, and ultimately for the rest of the world as well. AES Encryption Algorithm. Suppose Bob wanted to send a message to Alice. Bob’s unencrypted message is first broken down into 128-bit chunks. The bytes (16 in all) in a given chunk are then organized as a 4x4 matrix. A shift row transformation is a matrix function that is fundamental to an AES cypher. The function shifts the bytes in each row of a matrix by a specified offset given by the encryption technique, as its name suggests. The first row of the matrix is left unaltered for AES. Each byte in the second row is shifted to the left one position.AES Ohio inaugurates Smart Operations Center to fulfil digital transformation journey.
