A secure microcontroller for controlling devices in automobiles comprises a semiconductor substrate, memory elements, at least one internal bus, at least one 8/16/32/64-bit microcontroller core, one or more data interfaces and at least one quantum process-based generator for true random numbers. The memory elements, the data interface, the quantum process-based generator and the microcontroller core are connected to the internal bus. The quantum process-based generator generates and provides a random number at the request of the microcontroller core. The microcontroller core generates a key using a program from one or more of its memory elements and the random number. The microcontroller core uses a program from one or more of its memory elements and the key to encrypt and decrypt data which it exchanges with devices external to the secure microcontroller. The semiconductor substrate integrally comprises the sub-devices of the secure microcontroller mentioned herein.
