1. A control device for a motor vehicle, the control device comprising:
a printed circuit board having at least two microprocessors for providing functions of the control device, the at least two microprocessors including a first microprocessor and a second microprocessor,
wherein a security function of the functions is subject to a first security requirement that is greater than a second security requirement that applies to at least one other function of the functions,
wherein the printed circuit board includes a security area, in which components are provided for performing the security function and are configured to fulfill the first security requirement, the components including the first microprocessor,
wherein a communication of the first microprocessor into and out of the security area uses at least partially the printed circuit board, the communication being end-to-end (E2E) encrypted, and
wherein the second microprocessor does not meet the first security requirement and provides the at least one other function outside the security area, the second microprocessor being arranged on the printed circuit board.
