Abstract

A method for carrying out a secured startup sequence of a control unit, which includes a host that is configured to execute a loader program and one or multiple application programs, and a hardware security module (HSM) which includes a program memory and a data memory. The method includes a starting of the host and of the HSM; an authentication of the loader program by the HSM with the aid of a loader program signature stored in the program memory of the HSM; and, an execution of the loader program by the host if the authentication of the loader program is successful.
