Abstract

Provided is a method for the secure, computer-aided execution of program instructions of an application, including the following method steps. The method includes a step of switching on a learning mode of an execution environment. The method includes a further step of performing the application in the execution environment while the learning mode is switched on, wherein program instructions of the application are performed for a selected predetermined application scenario and the execution environment assigns a first application scenario-specific validity information to the performed program instructions. The method includes a step of switching on a working mode of the execution environment, wherein, in the working mode, the execution environment checks the first validity information of the program instructions, and wherein the execution environment executes the program instructions as a function of their validity information.
