ABSTRACT:
The present disclosure relates generally to semiconductor devices and related methods of operation. A semiconductor device is disclosed that comprises at least one cipher interface (126, 128) to a plurality of different cipher hardware modules (112, 114, 116) and central mode control logic (130-138, 106) responsive to the at least one cipher interface (126, 128). The central mode control logic (130-138, 106) is configured to provide a cipher operation in accordance with a selected cipher mode (104) in connection with at least one of the plurality of different cipher hardware modules (112, 114, 116).
