Abstract: A memory device includes a memory area directly inaccessible from an electronic device; a secure control section that manages access to this memory area; and a device control section that communicates with the electronic device and transfers a request of the electronic device to the secure control section. The secure control section temporarily delegates, to a device control section, access rights to the memory area if there is write/read request of large capacity data from an authenticated electronic device, and the device control section to which this access rights have been delegated write/read data sent from the electronic device into/from the memory area by burst transfer.

Abstract: The present application is to make an information storage device (card) with a plurality of communication functions perform a process by one of the communication functions in cooperation with another process performed by the other communication function. A card 30 includes contactless communication means and contact communication means so as to execute only one of a process using contactless communication and a process using contact communication at one and the same time. The card 30 further includes processing means 33 and status change means 31. The processing means 33 executes processes by contactless communication and contact communication. The status change means 31 gives a response, in terms of an execution status of a contactless communication process, when the status change means 31 receives a check request command for inquiring a condition of the contactless communication process from a card supervision portion 12 through the contact communication means.

Abstract: An object of the invention is to provide a memory device that is capable of writing large-capacity data into and reading them from a secure area within a short time. A memory device 10 provided by the invention is furnished with: a memory area 51 directly inaccessible from an electronic device 60; a secure control section 42 that manages access to this memory area 51; and a device control section 20 that communicates with the electronic device and transfers a request of the electronic device to the secure control section 42. The secure control section 42 temporarily delegates, to a device control section 20, 21, access rights to the memory area 51 if there is a write/read request of large capacity data from an authenticated electronic device 60, and the device control section 21 to which this access rights have been delegated writes/reads data sent from the electronic device 60 into/from the memory area 51 by burst transfer.

Abstract: It is an object of the invention to provide a memory device including a memory area having a large storage capacity and an equal security level to that of a Smart card. A semiconductor memory card 10 that can be attached to and detached from an electronic device is provided with first memory 50 of non-tamper-resistance having usual areas 52 and 53 that can be accessed from the electronic device and a secure area 51 that cannot directly be accessed from the electronic device, and second memory 41 of tamper resistance that cannot directly be accessed from the electronic device, wherein access to the secure area 51 of the first memory 50 can be made only through a secure control section 30 for managing access to the second memory 41. The secure area 51 cannot directly be accessed by an external device and therefore has the higher security level than the authentication area 52. Since the secure area 51 is placed in the non-tamper-resistant memory 50, a large storage capacity can be reserved.

Abstract: An information processing apparatus is disclosed capable of using application programs of both a cellular phone and a non-contact card type terminal in cooperation, and performing a process request with respect to a portable terminal in response to a command received by the non-contact card type terminal from a communication terminal. When a communication terminal 30 requests a second device (SE: non-contact card type terminal) 20 of an information processing apparatus (hybrid portable communication terminal) 70 to process data in response to a predetermined command in a predetermined non-contact communication system, a command transmission request is transmitted beforehand with respect to a first device (PTD: cellular phone) 10 of the information processing apparatus in another non-contact communication system.

Abstract: A file management method, whereby inconsistencies can be prevented between a file recorded in a memory card and the file management information that a terminal apparatus manages, without leaking the information of a file made and stored in an in-card processing system. According to this method, a flash memory accessible from two processing systems 100 and 300 is provided. First processing system 100 requests a reservation of an use area of flash memory 200a to second processing system 300, which, upon receiving the request, implements a reservation processing for an area of the memory section and reflects the information of the reserve area upon file management section 230. First processing system 100 performs the processing of writing data into the area reserved by second processing system 300. Inconsistencies between the file management information that a terminal manages and a file actually recorded into the memory section of a secure card can be prevented.

Abstract: With commands from a terminal divided into a command to designate an access area and a command to gain access, the terminal adds verification data of the terminal to an argument of the command to gain access, and it is thereby possible to verify the identity of a terminal application that issues the command to designate an access area, a terminal application that issues the command to gain access, and a terminal application that holds a verification key.

Abstract: The present invention provides a memory device that can safely hold much data necessary for using an Application (AP) therein. In the present invention, a memory device includes a first tamper resistant memory 41 that cannot be accessed directly by an electronic device and a second non-tamper resistant memory that cannot be directly accessed by the electronic device. The second memory is used to save data stored in the first memory 41 to. In this memory device, since data necessary for using many APs can be safely held in the device, any terminal device satisfying authorizing conditions can use the data held therein.

Abstract: One objective of the invention is to provide a hybrid portable communication terminal, as a data processing apparatus, that can employ together application programs for both a portable telephone and a contactless card terminal and that can communicate with an external device in accordance with a predetermined protocol by using, as needed, an appropriate application program, while another other objective is to permit a local server to identify each terminal.

Abstract: A system includes server 10 that manages data and check information for checking damage to the data, terminal apparatus 20 that acquires the data and the check information from server 10, and memory device 30 that stores the data acquired by terminal apparatus 20 into non-tamper-resistant memory area 31 and the check information acquired by terminal apparatus 20 into tamper-resistant memory area 32. Memory device 30 detects data in which data damage has occurred using the check information. Terminal apparatus 20 acquires the detected data from server 10, and memory device 30 repairs the data damage using the data acquired by terminal apparatus 20. This improves the storage efficiency of memory device 30, and furthermore, reduces the data communication time taken for acquiring normal data for repair from server 10.
