摘要： A secure LSI device 1 includes an encryption section 2 for encrypting a program, and an external I/F 50 for inputting/outputting a program or data from/to an external memory 100. In the encryption section 2, the operation of a private key arithmetic processing section 20 is prohibited with respect to a sequence whose execution is determined by a key-generation/update sequencer 30 to be impermissible. In the external I/F 50, a program processing section 51 and a data processing section 55 are structured independently from each other.

摘要： During initial start-up of an optical communication system, an ASE reference span loss is calculated based on transmitting power and received power of ASE light generated by an optical amplifier, and an OSC reference span loss is calculated based on the transmitting power and the received power of OSC light. During normal operation of the optical communication system, a span loss is calculated using the OSC light, and an amount of change in the span loss representing a difference between the span loss and the OSC reference span loss is calculated. A current span loss between a transmitting station and a receiving station is calculated by adding the amount of change in the span loss to the ASE reference span loss.

摘要： A system including a secure LSI 1 establishes a communication path to/from a server 3 (UD1), and receives a common key-encrypted program generated by encryption with a common key and transmitted from the server 3 (UD6 and UD7). The received common key-encrypted program is decrypted to generate a raw program, and the raw program is re-encrypted with an inherent key to newly generate an inherent key-encrypted program, which is stored in an external memory.

摘要： A data processing apparatus is capable of playing back contents stored in a specified area in a recording medium. The recording medium stores content data and management information for managing the content data. When playing back a content which is managed by the management information on the recording medium but of which entity data is not present in the specified area of the recording medium, the data processing apparatus, searches, for the content, the other area of the recording medium with a search section. When the corresponding content is found, the link information setting section sets the link information (symbolic link, shortcut, etc.) on the recording medium so that the content can be accessed with the management information.

摘要： A predetermined number of erasable blocks positioned at a start of a volume area in a semiconductor memory card are provided so as to include volume management information. A user area following the volume management information includes a plurality of clusters. A data length NOM of an area from a master boot record & partition table sector to a partition boot sector is determined so that the plurality of clusters in the user area are not arranged so as to straddle erasable block boundaries. Since cluster boundaries and erasable block boundaries in the user area are aligned, there is no need to perform wasteful processing in which two erasable blocks are erased to rewrite one cluster.

摘要： An information recording medium includes a data storage section having a plurality of recording regions for storing data, and a region information storing section operable to store information about each recording region in the data storage section. The region information storing section stores information about a recording region (for example, a recording region has been accessed finally) which is set first as an accessible region when the information recording medium is initialized at the next time among a plurality of recording regions in the data storage section. A data processing apparatus refers to the information about the recording region and changes over a recording region to the recording region specified by the information about the recording region just after initialization of the recording medium.

摘要： The present invention is directed to an optical space switch accommodating a plurality of input light paths and output light paths. The optical space switch comprises a plurality of polarization control optical switches, each consisting essentially of: polarization control means having elements, one for each input light path, for rotating through 90° the polarizing direction of light information incident from each input light path or otherwise retaining the polarizing direction thereof for output; and a light path routing element for routing the light path for the light information output from the polarization control means in accordance with the polarizing direction of the light information. These polarization control optical switches are arranged in a matrix pattern or coupled in cascade to implement a polarization control optical space switch.
