APPARATUS FOR INJECTING FAULT INTO SMART CARD CRYPTO CALCULATION AND METHOD THEREOF

摘要

An apparatus for controlling injection of an error into a controlled device and a method thereof are disclosed. An apparatus for controlling injection of an error according to an embodiment of the present invention includes: an error injecting unit which injects a predetermined error into a controlled device to cause the controlled device to generate error information; a controlled device state sensing unit which senses whether the controlled device is in an inoperable state; and a control unit which extracts secret information of the controlled device using the error information generated by the controlled device, and initializes the controlled device when it is sensed that the controlled device is in an inoperable state. The apparatus additionally includes a communication control unit which provides the control unit with the error information generated by the controlled device and initializes the controlled device using an initialization command received from the control unit. Therefore, a process of repeated error injection and information extraction can be automated to minimize user intervention, thereby improving user convenience.
