Input and Output Block Conventions for AES Encryption Algorithms
B. R. Gladman · 1999
1. Cryptographic algorithms operate in computer memory and transform memory blocks for inputs, outputs and keys. When these values need to be calculated consistently in many different processor environments it is necessary to have precise definitions of how they are to be interpreted and used. This has been a source of difficulty in the AES effort so far [1, 2] and has also been the subject of proposals for improvement in the first round comments [3].
