Abstract:
1. A method of safeguarding at least one safety-critical program part against inadvertent execution in a processor, comprising: providing a first memory sector and a second memory sector in a program memory, wherein the at least one safety-critical program part is contained in the second memory sector, and wherein at least one further program part is contained in the first memory sector, and wherein the first memory sector is configured to be executed prior to the second memory sector; executing the at least one further program part, wherein the at least one further program part includes a routine for generating a pattern; and at least at one point in time after the pattern is configured to be generated, checking whether the pattern is present; wherein a program code for resetting the processor is stored in a section of the program memory corresponding to a chronological execution point prior to the safety-critical program part.
