摘要:
A technology is provided to improve tamper resistance in encrypting data to be secured and inputting/outputting the data between a recording device and a host device. When the recording device issues an input/output command to a storage device to input/output data to be secured, the recording device attaches an ID to the command to identify to which cryptographic input/output processing the command belongs. Upon reception of a sequence command, the storage device receives the command if its ID has been allocated and the command is verified to have been issued in the correct sequence. The sequence ID is used to identify a process system while appropriately managing the steps of executing commands.

A controller of a recording device issues a secure command to a storage device, and then waits the time estimated necessary for the storage device to execute the secure command before issuing the next secure command. When a controller of the storage device is executing the previous command, it notifies the recording device of being in process. When the previous command has been completed normally, the controller moves to the next process. Information for estimating the execution time of the command is obtained from the storage device in advance.

A data storage device includes a secure data storage portion including a log memory. The log memory is formed of a plurality of banks, and stores history information in the plurality of banks in a ring-like fashion. The plurality of banks are designated by addresses (0-(N−1)), respectively. Each of the items of the history information respectively stored in the banks includes a management number region, a license ID (LID) region, a Ks2x region, an ST1 region, an ST2 region, a KPcmy region and a LBA region.

A data storage device includes a secure data storage portion including a log memory. The log memory is formed of a plurality of banks, and stores history information in the plurality of banks in a ring-like fashion. The plurality of banks are designated by addresses (0−(N−1)), respectively. Each of the items of the history information respectively stored in the banks includes a management number region, a license ID (LID) region, a Ks2x region, an ST1 region, an ST2 region, a KPcmy region and a LBA region.

A log region of a memory card includes a plurality of log entries and a plurality of administration information storage units. Each of the plurality of log entries includes a license ID region, a Ks2w region, a status region and a KPcmy region. The status region includes a ST1 region and a ST2 region to store the communication status. The license ID region stores a license ID. The Ks2w region stores a session key. The KPcmy region stores a class public encryption key of a memory card. The administration information storage unit stores the last record sequence number corresponding to the log entry storing history information of the latest communication.

A decryption processing unit decrypts encrypted content data using a license key Kc. When an elapsed time after reception of the license key (Kc) does not exceed a hold time at a time of the license key (Kc) included in reproduction control information (ACp), reproduction of encrypted content data continues. When the elapsed time exceeds the hold time at a time, the license key (Kc) is discarded, and a reproduction control unit again obtains a license key (Kc) from a memory card. Discarding and reobtaining license key (Kc) continues until an allowable output count of license key (Kc) from the memory card becomes zero. As a result, a reproduction time of encrypted content data can be controlled safely.

Provided is a plant cultivation device that improves cultivation efficiency and usability. A plant cultivation device comprises: a rack unit provided with cultivation racks on which cultivation units accommodating plants are stored as culture medium units; and a conveying device which moves along a horizontal movement path defined by a guide rail, and performs transport of the culture medium units and loading/unloading of the culture medium units to/from the cultivation racks. Multiple cultivation racks constitute a cultivation rack row, in which the cultivation racks are arranged at multiple levels in an up-down direction. The rack unit comprises: a cultivation storage constituted of multiple cultivation rack rows; and a loading/unloading station having a stock rack row, in which the holding frames of cultivation units not accommodating plants are stored as empty units. The transport device performs loading/unloading of the holding frames to/from the stock rack row.
摘要:
A user can watch desired content among a plurality of encrypted contents recorded in a storage apparatus having a large capacity recording medium when the user wants to watch. Usage Pass (UP) necessary for watching content and encrypted content are recorded in a rental storage apparatus. The UP is in an invalid state when the storage apparatus is rented, and processing for validating the corresponding UP is executed between the storage apparatus and a host apparatus through which content is watched to thereby make content watchable. A history that processing for validating the UP is executed is recorded in the storage apparatus. A service provider bills a content use fee to the user based on the history of the storage apparatus.
摘要:
The reliability of a semiconductor device is improved. A sealing resin (sealed body) is formed between a sub-substrate (first base member) and a base substrate (second base member) that are provided individually and distinctly to be integrated therewith, and then, the sub-substrate is electrically coupled to the second base member. As a means for electrically coupling the sub-substrate to the base substrate, lands (first lands) formed on the sub-substrate and lands (second lands) formed on the base substrate are disposed such that the respective positions thereof are aligned. After through holes are formed from the lands of the sub-substrate toward the lands of the base substrate, a solder member (conductive member) is formed in each of the through holes.

A first conductive member made of metal is provided over a first wiring substrate, which is a mounting substrate in the lower tier, a through hole is provided in a second wiring substrate, which is a mounting substrate in the upper tier, at a position corresponding to the first conductive member in a plan view, and a wiring is exposed at the sidewall of the through hole. The first conductive member is inserted into the through hole on the corresponding first wiring substrate side and the first wiring substrate and the second wiring substrate are electrically coupled by filling the through hole with a second conductive member. an electrode pad that is electrically coupled to the second conductive member and over which a semiconductor member in the upper tier is mounted is formed on the main surface side of the second wiring substrate.
