Abstract: 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.

Abstract: 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.

Abstract: When direct communication is performed between a cellular phone 2a having an IC card 1a inserted in its slot and a cellular phone 2b having an IC card 1b inserted in its slot, the IC cards 1a and 1b perform mutual authentication, and then notify each other of the IDs of the IC cards and the connection information of the cellular phones. Subsequently, one IC card 1 capable of connecting to a server 3 performs mutual authentication with the server 3, and then notifies the server 3 of the ID and the connection information concerning the other IC card. Thus, even if the other IC card is in a state where it cannot directly communicate with the server 3, the ID and the connection information concerning the other IC card can be managed in the server 3.
