Abstract: A device includes a safety domain having a processing unit and a memory and is configured to provide at least one functionality and to implement one more safety measures for detecting faults. The safety domain is configured to transmit at least one alarm signal indicating one or more detected errors in response to detecting the faults. The device further includes a security domain having a processing unit and a memory and is configured to provide cryptographic services and to obtain alarm signals. The security domain is configured to perform security-related operations in a secure state in response to obtaining an alarm signal from the safety domain.

Abstract: A non-volatile memory (NVM) system external to a processor comprising an NVM and a memory controller may perform various aspects of the techniques. The NVM may store a first cryptographic signature and first data. The memory controller may, responsive to a first write request to write updated data to at least a portion of the NVM, to store the updated data in the NVM along with the first data to create second data. The memory controller may also generate, a second cryptographic signature that always differs from the first cryptographic signature, and store the second cryptographic signature as a current cryptographic signature. The memory controller may further output, to the processor, the current cryptographic signature as a reference signature, where the memory controller always replaces the current cryptographic signature, with cryptographic properties, whenever the NVM is written to and does not otherwise permit writing the current cryptographic signature.

Abstract: Embodiments related to a processing unit and a first information storage are described and depicted. First information is provided from a first unit into a first information storage for performing a first operation of the processing unit. During the first operation of the processing unit second information is transferred between the processing unit and the first information storage. The first information storage comprises during the first operation of the processing unit an access protection for the first unit.

Abstract: A device includes a non-volatile memory and a control unit, wherein the control unit is configured to change over programming of data of the non-volatile memory from a first programming mode to a second, different programming mode based on the occurrence of a control signal.
