Abstract
One of the criteria for selecting substitutions used in block ciphers is the absence of fixed points. This paper
shows that this criterion must be extended taking into consideration mixing key function. It is shown that
modulo addition has more advantages than XOR operation. It is shown in practice that encryption procedure
of AES has a natural isomorphic form when fixed points are reached.
