Abstract:
A program execution device capable of protecting a program against unauthorized analysis and alteration is provided. The program execution device includes an execution unit, a first protection unit, and a second protection unit. The execution unit executes a first program and a second program, and is connected with an external device that is capable of controlling the execution. The first protection unit disconnects the execution unit from the external device while the execution unit is executing the first program. The second protection unit protects the first program while the execution unit is executing the second program.

Claim (Index 15):
A method for operating a portable terminal having a processor executing 1) a first program component for operating in a secure processing mode and performing tamper detection, and 2) a second program component for operating in a normal processing mode and performing a task, and a hardware memory storing at least the second program component, the method comprising:\n executing the first program component by the processor for determining whether at least part of the second program component is tampered with, by using a tamper detection value and while operating in the secure processing mode; and executing the second program component by the processor after the processor determines the second program component is not tampered, wherein the first program component operated in the secure processing mode cannot be accessed from the second program component operated in the normal processing mode.
