Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a digital signature generating system that is secure and effective against power analysis attacks or the like. SOLUTION: The authentication system and a method for signing data use a hardware software partitioned approach. The processing process is divided into a plurality of steps, and some step parts are executed in parallel. Thus, the power consumed by each processing means is consumed in a way of being masked. Consequently, the power consumed by one processing means is masked by the power consumed by the other processing means. Then the system is secured from simple power analysis attacks by hackers.
