Abstract: In a portable terminal 10 incorporating a non-contact IC 20, the non-contact IC 20 includes a card appli storage region 24 in which a card appli is stored, and the portable terminal 10 includes an appli storage region 15 in which appli's inclusive of the card appli are stored. When the non-contact IC 20 executes non-contact communication with an external R/W 30 to store the card appli selected by the external R/W 30 in the card appli storage region, a storage region for the card appli is ensured in such a manner that the card appli already stored in the appli storage region 24 is saved into the appli storage region 15. The saving of the card appli stored in the card appli storage region 24 of the non-contact IC 20 is executed using a trilateral communicating function.

Abstract: An information-communication terminal device maintaining a low cost of a charger in the case of backup for the device at a charging time, having a high performance security at the backup and allowing users to easily handle the security control after the backup. A charger (107) in the information communication terminal device is charged electric power from a charger (3). An access-release demanding section (105) receives ID data from the charger (3) during the charging time, and demands to release access control to an IC-card-function installed memory card (2). After the IC card-function installed memory card (2) releases the access control, a control section (101) carries out the backup or restore to the IC card-function installed memory card (2).

Abstract: An object of the present invention is to provide an information processing apparatus in which a secure CPU and a non-secure CPU are included, that is capable of reliably detecting falsification of programs. The information processing apparatus according to the present invention includes a secure CPU 1, a non-secure CPU 2, a nonvolatile memory 3, a boot ROM 11, and a RAM 12. The secure CPU 1 verifies the presence or absence of falsification of various programs stored in the nonvolatile memory 3 with reference to a first falsification verification program stored in the boot ROM 11, according to a verification result, and loads a secure CPU target program 31 stored in the nonvolatile memory 3 into the RAM 12, and outputs a non-secure CPU target program stored in the nonvolatile memory 3 to the non-secure CPU 2 with reference to a load program loaded in the RAM 12.

Abstract: An information processing terminal that performs falsification verification at the time of bootstrapping thereof includes: a state sensor that senses a connection of an external connector or a data reception via the external connector, to judge whether or not a program stored in the information processing terminal is in a rewritable state; a flag storage that stores a flag referred to at the time of bootstrapping of the information processing terminal therein; a flag controller that turns on the flag according to a judged result that the program is in the rewritable state by the state sensor to record the turn-on flag in the flag storage; and a falsification verifier that judges whether or not it is necessary to carry out falsification verification according to a status of the flag, and performs falsification verification of the program only in the case in which the flag in the flag storage is turned on, at the time of bootstrapping of the information processing terminal.

Abstract: A reader/writer device performs noncontact communication with a noncontact IC card section (400) to which power is supplied from a power storage section (310) of a portable terminal (300) whereupon the card section is mounted. In the reader/writer device (100), a noncontact communication section (110) transmits and receives information to and from the IC card section (400) by noncontact communication, and a noncontact charging section (120) supplies power to the power storage section (310) in noncontact manner. When noncontact communication with the IC card section (400) cannot be performed by controlling the noncontact communication section (110), a contactless communication/charging control section (130) controls the noncontact charging section (120) to charge the power storage section (310) of the portable terminal (300) in noncontact manner, then, controls the noncontact communication section (110) again to perform noncontact communication.

Abstract: An application management device can collectively manage and receive providing service as to applications on different platforms in a mobile terminal device equipped with an IC card, such as a card application used for the same service, a native application, and “Java” (registered trademark) application. This application management device (400) is applied to a mobile terminal device (100) to manage a plurality of applications used for service by means of an IC function of an IC card (200) set at the mobile terminal device (100). A table memory unit (406) stores a plurality of applications comprised of a card application of the card (200), a native application dependent on an inherent platform in the mobile terminal device (100) and a non-native application in association with a plurality of application names indicative of a plurality of the applications and a service ID indicative of service carried out in cooperation with a plurality of applications.

Abstract: A mobile terminal system is provided whereby, when a memory card or memory card with an IC function inserted in a mobile terminal apparatus is removed, a function of at least one of the apparatus itself and/or the memory card is locked easily by means of an intuitive operation by the user. This mobile terminal system (100) has a memory card (300) and a mobile terminal (200) in which the memory card (300) is inserted in a removable fashion. The mobile terminal (200) detects lengthy depression of a pressure section (202) pressed by the user by means of a long-depression detection section (204), and detects insertion of the memory card (300) inserted into a slot section (206) in a removable fashion by means of a card insertion/removal detection section (208). A locking execution section (218) locks or unlocks a function of at least one of the terminal (200) itself and/or the memory card (300).

Abstract: In a set-up phase, the base station formulates the secret key S and holds it in secret. The secret information Si which are obtained by dividing the secret key S are distributed in secret to respective terminals 1 to 5 by using cryptographic communication means. In a preparatory phase, the base station 0 broadcasts the preparatory information C1(=gk modp), the exclusive information C2(=y5k modp), the ciphertext C3(=M×K modp), and the particular terminal number 5 to all terminals. In a key sharing phase, the terminal 1 calculates a product of C1{circumflex over ( )}(&lgr;(1, &Lgr;) modq) modp and C2{circumflex over ( )}(&lgr;(5, &Lgr;) modq) modp by using the preparatory information C1 and the exclusive information C2 to obtain K and then calculates M, which are common data to the base station 0, by dividing the ciphertext C3 by K. The terminals 2 to 4 execute similar calculations. As a result, the terminals 1 to 4 can share mutually the common data M.
