Abstract(in English) | This paper mainly focuses on note-based types of prepaid electronic money systems. Assuming compromise of cryptographic algorithms and/or devices used in such electronic money systems, we evaluate the security against forgery of payment data and discuss operational countermeasures against such a forgery attack. As the results, we clarify that the note-based systems are more secure than the balance-based ones against the attack if the features of the systems, e.g. online/offline and open/closed-loop, are the same in these systems. We also find that the condition of payment data verification, i.e. online/offline, has a significant impact on the successfulness of the forgery attack. Moreover we discuss the limitation of effects of the operational countermeasures in the note-based systems under the assumption that the cryptographic algorithms and/or devices are compromised. |
