摘要
An apparatus for protecting against external attacks for a processor based on an ARM core and a method using the same are provided. A method for protecting against external attacks for a processor based on an ARM core in accordance with an embodiment of the present invention includes: setting up a register using a reset handler, which is executed first within a boot image; generating a control signal for protecting against external attacks using any one of an external debug request signal and an output signal of the register; and blocking a JTAG interface used for JTAG communication with the processor based on the ARM core according to the control signal for protecting against external attacks.
