Abstract
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.
