Zusammenfassung:	An apparatus and method for providing a security keypad are provided. The apparatus for providing a security keypad includes a coordinate generation unit, a keypad output unit, and a key value processing unit. The coordinate generation unit computes a displacement by which a security keypad is to be shifted, and rearranges at least some of keys included in the security keypad by shifting the at least some keys so that the central axis of the security keypad is translated by the displacement. The keypad output unit displays the rearranged security keypad to a user. The key value processing unit processes key values in response to the user's input to the rearranged security keypad, and transfers the processed key values to an application for which the rearranged, security keypad is used.
