    Abstract: PURPOSE: An apparatus for protecting against external attack for a processor based on an ARM core and a method using the same are provided to assure security simply as using a joint task action group (JTAG) in an arm core series system which provides debugging function using JTAG. CONSTITUTION: A JTAG interface (110) is connected to an ARM core-based processor (140) for JTAG communication. A control signal generator (120) generates an external attack prevention control signal. An interception unit (130) intercepts the JTAG interface on the basis of the external attack prevention control signal. The external attack prevention control signal is activated, according to the set value of a register (180). When the external attack prevention control signal is activated, multiplexers (104,106) of the interception unit select a ground signal which is a dummy signal.
