摘要： PROBLEM TO BE SOLVED: To improve tamper resistance when encrypting, and inputting/outputting data to be concealed between a recorder and a host device. SOLUTION: When the recorder issues an input/output command of the data to be concealed to a storage device, the recorder adds an ID for identifying a cipher input/output process to which the command belongs, and transmits it to the storage device (S700). When the storage device receives a sequence command (S702), the storage device receives the command (S708) when the ID is secured (Y at S704) and when it is confirmed that command issue order is rightful (Y at S706). While identifying a processing system by a sequence ID, an execution procedure of the command is properly managed. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To improve the processing efficiency at the time of encrypting and inputting/outputting data to be kept confidential between a recording device and a host device. SOLUTION: The controller of the recording device stands by, after issuing a secure command to a storage device, for the time estimated to be necessary for execution of the secure command by the storage device, and then issues the next secure command (S500). The controller of the storage device reports, when a just before command is under execution, the effect of in progress to the recording device (S508), and transfers to the next processing when the execution of the just before command is normally ended. Information for estimating the execution time of the command is preliminarily acquired from the storage device. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a technique for adequately easily implementing timeout control when executing command processing successively.
SOLUTION: When successively issuing multiple commands to a hard disk, the timeout time of the command processing is set on the basis of time intervals of the commands (S400). An allowable time is computed by subtracting an estimated access time from the timeout time (S404), which is informed when transmitting the command to the hard disk (S408). When determined that the processing time of the command reaches the timeout time in executing the command processing, the processing of the command is forcibly terminated. Consequently, the successive processing can be implemented smoothly.

摘要： PROBLEM TO BE SOLVED: To provide a data recording device in which a license under transmitting/receiving can be speedily specified out of a number of recorded licenses and especially, the protection of the license and the acceleration of re-processing can be made compatible when abnormality occurs during transmitting/receiving of the license. SOLUTION: A controller 214 in hard disks (HD) 20 and 21 as the data recording device stores the license containing a contents key or the like for decrypting encrypted contents data in a secure data storage part 250. The license is managed by LBA (address information) within the secure data storage part 250 and the LBA to store the license under transmitting/receiving is stored as a log in a log memory within the secure data storage part 250. When abnormality occurs during transmitting/receiving, on the basis of the LBA stored in the log memory, the license under transmitting/receiving is specified. COPYRIGHT: (C)2003,JPO
