    摘要： Between an IC card (1) and a electronic ticket server (2), upon purchasing an electronic ticket a public key cryptosystem is employed for a mutual authentication to keep a strict security, and a shared secret between the electronic ticket and a ticket collecting machine is sent on a secure channel as well as the electronic ticket. Upon usage of the electronic ticket, the IC card (1) and the ticket collecting machine (6) mutually judge whether they carry out the mutual authentication by using a public key cryptosystem or a symmetric key cryptosystem. When they determine to use the symmetric key cryptosystem, they carry out the mutual authentication by using the shared secret exchanged beforehand. When they determine to use the public key cryptosystem, they carry out the mutual authentication by using the same method as that used upon purchasing the electronic ticket. This method of mutual authentication can dynamically switch cryptosystems for cryptographic communication between the IC cards or between the IC card and a tamper resistant device having an equivalent function to an IC card installed in related servers or the ticket collecting machine, based on their judgment of the types of bearers, the required degree of security and the required processing speed.

    摘要： Each IC card 1 notifies a server 3 of the ID of the IC card and the connection information of a terminal device to which the IC card is connected. The server 3 stores the ID and the connection information in a database 4 while associating the ID and the connection information with each other. When an IC card 1 communicates with another IC card, the IC card 1 requests the connection information concerning the destination IC card from the server 3 while specifying the ID of this IC card. The server 3 searches the database 4 for the connection information corresponding to the ID specified by the request, and notifies the requesting IC card 1 of the acquired connection information. This enables communications between IC cards even if the terminal device to which a destination IC card is connected has been changed in the past.

    摘要： An autonomous integrated circuit card includes a logic external communication interface which directly communicates with a communication device connected to an integrated circuit card terminal main body via a network, in addition to a host device interface connected to an integrated card reader/writer via a physical layer. A communication control unit includes a software module which directly communicates with the communication device via the external communication interface. A central processing unit performs authentication via the communication control unit and reads value information stored in a nonvolatile memory. Further, the central processing unit encrypts the read value information by use of an encryption processing unit and directly transmits the encrypted value information to the communication device via the communication control unit and the external communication interface.

    摘要： The present invention avoids duplication and loss of digital contents by a transmitter/receiver and a malicious third party when the digital contents are transmitted on a communication platform where direct communication is performed between IC cards. A data communications method relating to the present invention includes the steps of executing a predetermined command when an IC card 1a receives a predetermined trigger signal; storing a state of the IC card 1a before transmission of first digital contents; performing an encryption process on the first digital contents based on key information associated with the first digital contents; deleting the first digital contents from a holder 18 of the IC card 1a when a commit instruction indicating completion of a reception process on the encrypted first digital contents is received from a destination device 1b: and performing a return process to the state of the IC card 1a when a transmission process on the first digital contents is interrupted.
