Summary:The disclosure relates to a method for operating an ECU in a normal mode and in a protected mode. In protected mode a new security artifact is stored in a microcontroller. The second security artifactis transferred from the microcontroller to a microprocessor, wherein, after having received the second security artifact, the microprocessor uses the second security artifact for authenticating a program. 本公开涉及保护电子控制单元的方法，具体地，一种用于在正常模式和受保护模式下操作ECU的方法。在受保护模式下，将新的安全制品存储在微控制器中。将第二安全制品从微控制器传输到微处理器，其中，在接收到第二安全制品之后，微处理器使用第二安全制品来认证程序。
