Title: (EN) METHOD AND EXECUTION ENVIRONMENT FOR THE SECURE EXECUTION OF PROGRAM INSTRUCTIONS
(FR) PROCEDE ET ENVIRONNEMENT D'EXECUTION POUR EXECUTER DE FACON SECURISEE DES INSTRUCTIONS DE PROGRAMME
Abstract: front page image
(EN)

The invention relates to a method (100) for the secure, computer-aided
execution of program
instructions of an application, comprising the following method steps. The
method comprises a step of
switching on (110) a learning mode of an execution environment (400). The
method comprises a further
step of performing (120) the application in the execution environment (400)
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 (400) assigns
a first application
scenario-specific validity information to the performed program instructions
(210, 220, 310, 320). The
method comprises a step of switching on (130) a working mode of the execution
environment (400),
wherein, in the working mode, the execution environment (400) checks the first
validity information of
the program instructions, and wherein the execution environment (400) executes
the program
instructions as a function of their validity information.
