RotWord in Rijndael's Algorithm
Yes. See also en.wikipedia.org/wiki/Advanced_Encryption_Standard. There is a pseudo-code in NIST's AES standard document which is very helpful for implementors. I have a Python code that very closely follows that pseudo-code in s13.zetaboards.com/Crypto/7385224/1/. For details of the design of AES, see J. Daemen, V. Rijmen, The Design of Rijndael.
