    摘要: A contactless integrated circuit (IC) card for providing a high-grade random number with a simple configuration. A plurality of provisional random numbers are generated according to a part of calculations to be used for generation of a random number. The plurality of provisional random numbers generated are stored. A random number is generated on the basis of one of the provisional random numbers selected in sequential order.

    摘要: A semiconductor memory card that has a sufficient storage capacity when an electronic commerce (EC) application writes data to a storage is provided. A usage area for the EC application in EEPROM 3 in a tamper resistant module (TRM) 1 is expanded. The expansion is such that a partition generated in a flash memory 2 outside the TRM 1 is assigned to the EC application while a partition table is allocated in the internal EEPROM 3. Because the partition table is in the TRM 1, only a CPU 7 in the TRM 1 is able to access the generated partition table. Secrecy of stored contents increases because the access to the expanded area is limited to the CPU in the TRM 1.

    摘要: The present invention provides a semiconductor memory card which no longer allows an illegal practice of acquiring contents of a deleted file. Here, when a deletion event is generated, a deletion handler gives a priority to a null-clear operation of a file entry and a FAT for a file to be deleted over a null-clear operation to other constituents of the file. A null-clear operation to a file entity of the file is distributed to a plurality of event handlers including the deletion handler.

    摘要: A data distribution system is provided which generates outputs attribute data about multimedia data in advance and broadcasts the output attribute data together with the multimedia data so that the receiving terminal can grasp the outlines of the entire multimedia data and improve the visibility. A data broadcasting device (1) generates output attribute data about multimedia data in a data analyzing portion (13). The output attribute data exists alone or is embedded in the multimedia data. The multimedia data and the output attribute data are encoded in a protocol encoder (14) and broadcast from a transmitter (15). A receiving terminal device (2) receives the broadcast data in a tuner (21) and obtains the multimedia data and output attribute data in a tuner (21). When a data display portion (26) displays the obtained multimedia data, the output attribute data is referred to and information related to the multimedia data is displayed together with the multimedia data. A data analyzing portion (24) analyzes the multimedia data and extracts the output attribute data embedded therein.

    摘要: An IC card provided with a contact-type interface and a non-contact-type interface as the communication interface, and other electronic devices. The IC card identifies the kind of communication data communicated with an external device such as reader-writer, and decides on a communication interface that follows the identified communication data. Then, it is judged whether to switch the communication interface used communication for with the external device between the contact-type interface and the non-contact-type interface. And if it is decided to switch, the communication interface used for communication with the external device is switched.
