Abstract: The present invention provides an apparatus for obfuscating and restoring a program execution code. The apparatus for restoring an obfuscated program execution code may include a memory loading a program execution code obfuscated so as not to be executed before restoration from a storage medium; a restoring unit, not allowing access by a third party who is not a user of the apparatus, restoring the obfuscated program execution code delivered from the memory and directly delivering it to a central processing unit (CPU); and a CPU executing the restored program execution code. Thus, since the execution code order which shows the same operation as the original program execution cannot be known even by a third party who achieved and analyzed a program execution code executed in a single equipment, it is not possible to analyze the algorithm, etc. through program execution code analysis, and it is not possible to execute the achieved execution code at a different equipment. Accordingly, intellectual property right can be protected.

Abstract: A method performed by a fault management device including a microcontroller is provided. The method includes receiving fault information from a controller connected to the fault management device. The method also includes incrementing a first counter in response to receiving the fault information. The method additionally includes incrementing a second counter and initializing the first counter, when the first counter exceeds a first reference value. The method further includes incrementing a third counter and initializing the second counter, when the second counter exceeds a second reference value. When the fault management device does not receive the fault information for a first reference time or more, the first counter decrements.
