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.

Cryptography module for controlling device

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.

Efficient distribution of processes between a vehicle control computing device and a cryptographic module, and method for operation thereof

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.

Cryptography module and method for operating same

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.

Computing device and method for operating same

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.

A method for updating an embedded electronic control unit, including an update gateway requests from a hardware security module an update request destined for the electronic control unit, the update gateway receives from the hardware security module the update request, which is signed by the hardware security module, the update gateway creates a communication channel, based on a cryptographic identity of the update gateway, to a backend, the update gateway sends the update request to the backend, the update gateway receives from the backend via the communication channel an update ticket which corresponds to the update request and is signed by the backend, in addition to associated update data, validates the update data, initiates a validation of the update ticket, checks the result of the validation, and depending on the result, the update gateway updates the electronic control unit with the update data.

Method and update gateway for updating an embedded control unit

A method for authorizing a function of an embedded electronic control unit, including: a decision gateway requests from a hardware security module a function request destined for the electronic control unit, the decision gateway receives from the hardware security module the function request which is signed by the hardware security module, the decision gateway creates a communication channel, based on a cryptographic identity of the decision gateway, to a backend, the decision gateway sends the function request to the backend, the decision gateway receives from the backend via the communication channel a ticket which corresponds to the function request and is signed by the backend, and the decision gateway stores the ticket.
