A method for operating an electronic control unit (ECU) includes a normal mode and a protected mode. In the protected mode a new security artifact is stored in a microcontroller. The security artifact is transferred from the microcontroller to a microprocessor, and, after having received the security artifact, the microprocessor uses the security artifact for authenticating a program.

Method for protecting an electronic control unit

The present invention relates to a vehicle control unit that includes a microcontroller unit, a sealing controller unit including a memory for storing a validity state, an electrical connector configured to couple the microcontroller unit to the sealing controller unit, and a housing enclosing the microcontroller unit, the sealing controller unit, and the electrical connector. The microcontroller unit is configured to determine the validity state of the sealing controller unit via the electrical connector, and the sealing controller unit is configured to detect a mechanical change to the housing and to change the validity state when such a mechanical change is detected.
