Abstract: A Cryptographic Unit (CU) of a microcontroller, the CU including a first accelerator configured to generate first encrypted output data based on input data; and a second accelerator which is configured to be diversely implemented with respect to the first accelerator, and is configured to generate second encrypted output data based on the input data; and a comparator configured to compare a first comparator data obtained from the generation of the first encrypted output data with a second comparator data obtained from the generation of the second encrypted output data, and if the comparison indicates that the first and second comparator data differ, output an event signal pertaining to an event in a safety domain or a security domain.

Abstract: A method for processing data in a plurality of processing acts includes: configuring a plurality of processing circuits in a first configuration, in such a way that both a first and a second of the plurality of processing circuits execute a first of the plurality of processing acts; and configuring the plurality of processing circuits in a second configuration, in such a way that the first processing circuit executes a second processing act and the second processing circuit executes a third processing act, which is different than the second processing act. An apparatus is designed for carrying out the method.
