Patent number: 7721346Abstract: 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.Type: GrantFiled: March 26, 2004Date of Patent: May 18, 2010Assignees: Sanyo Electric Co., Ltd, Pioneer Corporation, Fujitsu Limited, Sharp Corporation, Hitachi Global Storage Technologies Japan, Ltd., Victor Company of Japan Limited, Phoenix Technologies K.K. of TokyoInventors: Yoshihiro Hori, Yuichi Kanai, Ryoji Ohno, Takeo Ohishi, Kenichiro Tada, Tatsuya Hirai, Masafumi Tsuru, Takayuki Hasebe

Patent number: 7058770Abstract: A recording area of a hard disk is managed by units. Each unit comprises physically continuous recording regions having predetermined size, and usage status of the unit is stored in an allocation unit (AU) management table. Data requiring a real time processing is stored in each unit. When the usage status of the unit is changed or modified due to the recording or deletion of data, the AU management table is updated and then information indicative of the fact that the AU management table has been updated is recorded. An apparatus where the final change is made is detected at the time the hard disk is inserted or a file system is initialized. And if the apparatus which last made the change adopts the file system which does not use the AU management table, then the table is reconfigured so as to retain the consistency of the AU management table.Type: GrantFiled: October 2, 2003Date of Patent: June 6, 2006Assignees: Sanyo Electric Co., Ltd., Sharp Corporation, Victor Company of Japan, Limited, Pioneer Corporation, Hitachi, Ltd., Fujitsu LimitedInventors: Yuichi Kanai, Yoshihiro Hori, Ryoji Ohno, Takeo Ohishi, Kenichiro Tada, Tatsuya Hirai, Jun Kamada
