  • Patent number: 8468094
    Abstract: An electronic value exchange system 100 comprises a mobile terminal 10 and a mobile terminal 20. The mobile terminal 10 causes a driver 12 to transmit an exchange offer message of electronic value V1, V2 to the mobile terminal 20. The mobile terminal 20 stores handlers that the driver 12 can execute in relationship to a message in a common table 221, and acquires a handler corresponding to the above-mentioned offer message, and notifies the exchange offer contents based on the handler to an application program 21. If the application program 21 consents to the offer contents according to the operation of a user, the electronic value V2 stored in an IC card 23 is transmitted to an IC card 13 via a driver 22 and the driver 12.

  • Patent number: 8306919
    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.

  • Patent number: 7896236
    Abstract: A portable terminal, when receiving an exchange offer message of electronic values from a portable terminal, notifies an application program of an exchange offer content based on a listener corresponding to the message. When the application program accepts this offer content and when electronic values are determined as exchange objects, the portable terminal returns an exchange confirmation message of the electronic values. When the portable terminal receives the exchange confirmation message, it notifies an application program of an exchange content based on a listener corresponding to the message. When the application program accepts the exchange content, the exchange transaction of electronic values is started.

  • Patent number: 7882030
    Abstract: 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.

  • Patent number: 7865438
    Abstract: A user device uses, instead of agreement information, only second session information contained in the agreement information, to generate an electronic signature for information containing the session information and information indicating an abort request, and outputs abort request information containing the session information, the information indicating the abort request, and the electronic signature, whereby transmission/reception can be performed without unnecessary information. Similarly, it may be configured to use only the second session information to generate an electronic signature for information containing the session information and information indicating a commitment request, and to output commitment request information containing the electronic signature. Since a third-party device defines a third session state as abort in correspondence to the second session information, it is able to manage states while appropriately discriminating a plurality of concurrent electronic value exchanges.

  • Patent number: 7861293
    Abstract: In a mobile terminal that performs transmission and reception of a message between an IC card and a terminal program, the security is improved by preventing an imposture of a source of a message or an interception of a message. A mobile terminal comprises an IC card and a terminal program. The terminal program generates a program identifier (i1:1) from a domain ID “i1” of the IC card and a port number “1” that can be updated in the IC card. Then, a message is transmitted, the source ID of which is the program identifier and the destination ID of which is the identifier “i1:0” of the IC card. Upon receipt of the message, the IC card collates the domain ID with the domain ID that the IC card has, as to the source ID. When they coincide, processing in accordance with the contents of the above-mentioned message is performed.

  • Patent number: 7590591
    Abstract: When a portable terminal receives a condition for an exchange object from a portable terminal, it selects electronic values as exchange objects, out of lists constituting the condition. An IC card deletes the electronic value and sends a message addressed to the portable terminal. An IC card deletes the electronic value in conjunction with fulfillment of a predetermined condition and thereafter sends a message addressed to the IC card. The IC card stores the electronic value in conjunction with fulfillment of a predetermined condition and sends a message addressed to the IC card. The IC card stores the electronic value.

  • Publication number: 20090199005
    Abstract: The security of an IC card is improved by managing success and failure in authentication individually for each terminal program. An IC card includes a random number generation section, a source authentication section, and a process execution section. Upon receipt of a message of type “1”, the random number generation section generates a random number n, and stores it in a random number storage section by associating the random number n with a source included in the message. Upon receipt of a message of type “2” from the source and in a case where the random number n corresponding to the source is stored, the source authentication section collates a value m calculated from an authentication key held by the IC card and the random number n with a value m included in the message of type “2”. When both values agree, upon receipt of a message of type “3” from the source, the process execution section executes a process in accordance with a type of the message.
