Abstract: A communication apparatus includes: a data generating unit that generates write data to be sent to any other communication apparatus at an arbitrary timing; a communication unit that repeatedly sends a read request to the other communication apparatus until the write data is generated and, at the same time, repeatedly receives a read response sent from the other communication apparatus in response to the read request; and a data acquisition unit that acquires read data, which is sent along with the read response by the other communication apparatus, when the read data is generated at an arbitrary timing by the other communication apparatus.

Abstract: An information processing apparatus includes a communication processing unit configured to communicate with an external communication device and a data processing unit configured to communicate with the communication processing unit via a wired data communication path. The data processing unit is configured to interpret address information received from the external communication device. The communication processing unit includes a memory where data transmitted and received between the external communication device and the data processing unit is temporarily stored. The communication processing unit further includes a control unit configured to control data writing in and data reading from the memory, perform an error check process by a code included in a received data from the external communication device, and transmit the address information received from the external communication device to the data processing unit without interpreting the address information.

Abstract: An information processing apparatus includes a communication processing unit configured to communicate with an external communication device; and a data processing unit configured to communicate with the communication processing unit and carry out data processing. The communication processing unit includes a memory where data transmitted and received between a communication device and the data processing unit is temporarily stored, and a control unit configured to control data writing and data reading. When a command packet received from the communication device is a data reading request, the control unit acquires data from the memory and transmits the data to the communication device. When the command packet received from the communication device is a data writing request, the control unit stores data in the memory, acquires data from the memory in response to the request from the data processing unit, and outputs the data to the data processing unit.

Abstract: The present invention relates to an electronic apparatus, an information processing method, and a program that allow a provision server of an application to be capable of easily causing an electronic apparatus having an IC chip to manage data. When a service-issuing command transmitted from a service-issuing terminal 11 is received, in a service-issuing function 21 of an IC card 2, information indicating a service data structure and a program describing a processing sequence that correspond to an identifier transmitted as a command parameter are acquired from a service definition database 23. In the service-issuing function 21, IC-card internal processing is performed, and a service data structure for managing data to be used for receiving the provision of a specific application is prepared in a file system 22. The present invention can be applied to an apparatus having an IC chip.

Abstract: An information processing device includes: a data storage portion that can store user data used in a particular non-contact communication service and management information to manage the user data in different storage areas corresponding to different encryption methods and that has a first storage area storing management information corresponding to a first encryption method; an issuing information receiver that receives issuing information encrypted with the first encryption method from an issuing device delivering the issuing information to issue management information corresponding to a second encryption method; an issuing information decryption portion that decrypts the received issuing information with the first encryption method, based on the management information corresponding to the first encryption method stored in the first storage area; and a management information issuing portion that, based on the decrypted issuing information, issues the management information corresponding to the second encryp

Abstract: A control unit of a communication device decrypts, when receiving via an antenna from a reader/writer a cipher key encrypted with a key same as a common key recorded in a recording unit by the reader/writer, the encrypted cipher key with the common key recorded in the recording unit, and when receiving via the antenna from the reader/writer a readout target address specifying a region of a data readout source in the recording unit encrypted with a cipher key same as the cipher key by the reader/writer, decrypting the encrypted readout target address with the cipher key, and transmitting the data recorded in the region specified by the readout target address obtained through decryption of the regions of the recording unit to the reader/writer via the antenna.

Abstract: A communication device includes an antenna for transmitting and receiving signals with a reader/writer of a service issuing terminal; a recording unit recorded with data, and also recorded with a pattern in which information specifying an authentication key and access attribute indicating whether or not a readout process or a write process on the data is possible using the authentication key are corresponded; and a control unit for, when receiving one or plural information specifying a region of the data from the reader/writer of the service issuing terminal via the antenna, holding the received one or plural information specifying the region of the data.

Abstract: A communication processing device includes a control unit for, when receiving an address update request signal including a segment identifier for identifying a segment address of a recording unit from a reader/writer, holding the segment identifier in a RAM, and when receiving a readout request signal including an offset address having the segment as a reference from the reader/writer, transmitting to the reader/writer data recorded in a region specified by an address having the offset address contained in the readout request signal as offset with the segment address identified in the segment identifier as a reference of the regions of the recording unit.
