Zusammenfassung:To implement a configuration of preventing a fraud regarding a transaction log regarding a transaction between an IC card and a reader/writer. The IC card receives log configuration information necessary for generating a transaction log from the reader/writer, generates the transaction log using the received data, executes signature processing for the generated transaction log to generate a transaction log with card signature, and transmits the generated transaction log with card signature to the reader/writer. Moreover, the IC card generates a transaction log with chain signature obtained by performing a new signature using an IC card-side immediately preceding transaction corresponding card signature and a reader/writer-side immediately preceding transaction corresponding reader/writer signature as signature target data, and transmits the transaction log with chain signature to the management server.
