<P>PROBLEM TO BE SOLVED: To easily identify an information processing device for an illegally utilized IC card, or the like. Ž<P>SOLUTION: A decoder 62 extracts a scramble key from information that is received and supplied by an unauthorized server 82 and includes the scramble key. A comparison section 161 compares ID information for identifying an IC card 142 held in advance with time information indicating clock time based on key output control data for controlling the output of the scramble key received and supplied by the unauthorized server 82. An output control section 162 controls the output of the scramble key, based on a comparison result by the comparison section 161. The present invention can be applied to, for example, the security module of the IC card, or the like for decoding an encrypted scramble key. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
