Abstract: A computing device, in particular, for a control unit of a motor vehicle. The computing device is configured to receive messages from at least one external unit. The computing device is configured to store the received messages at least temporarily and to transmit a plurality of the received messages to a cryptographic module, which is configured to execute a check of the transmitted messages.

Abstract: A cryptography module for a computing device. The cryptography module is designed to check at least one memory area of a memory device which the computing device may access, as the result of which a result of the check is obtained, and to store the result at least temporarily.

Abstract: A computing device that includes at least one processor core for executing a first computer program, the computing device being designed to access a memory device, in particular in order to load the first computer program. The computing device is designed to transmit a first control command, which characterizes the first computer program and/or a memory area of the memory device associated with the first computer program, to at least one cryptography module. The cryptography module is designed in particular to check the computer program, or the memory area of the memory device associated with the first computer program, characterized by the first control command, and the computing device is designed to execute the first computer program.

Abstract: A cryptography module for at least temporarily controlling an operation of at least one computing device. The cryptography module is designed to check at least one memory area of a memory unit capable of being accessed by the computing device, and to control the operation of the at least one computing device as a function of the check. The cryptography module is designed to receive a first control command from the computing device, which characterizes at least one memory area of the memory unit to be checked, and to check the memory area characterized by the first control command.
