| 1. An M6 block cipher system, comprising:
a rotate constant selector device selecting one or more rotate constants from a plurality of input rotate constants for output
based on a selection signal input thereto,
a rotate constant ordering device ordering the selected rotate constants and a common rotate constant input thereto based
on a received ordering signal,
an M6 core device generating one or more of an output signal, a validity signal and a round number based on the ordered rotate
constants and a plurality of input signals, and
a rotate constant scheduler device outputting the ordering signal to the rotate constant ordering device in response to the
selection signal and the round number.
