摘要： A device and method is provided for commonly and securely allowing, as access control on a memory card, a plurality of information processing apparatuses to lock/unlock the memory. On the basis of a lock command input from an information processing apparatus serving as a host, such as a PC, an information storage device, such as a memory card, determines whether (a) a standard lock key set serving as a key set prohibiting output or (b) an export lock key set serving as a key set permitting output is detected and stores corresponding key set information. Only when the export lock key set is detected, output is permitted provided that predetermined verification succeeds.

摘要： When a content is moved from a flash memory into a content database, a usage rule management program updates a variable seq-1, stored in a 0th defective block of a media defect list stored in the flash memory, to a new value seq-2. The usage rule management program calculates an MAC value (hash value) on the basis of the content stored in the data portion of the flash memory, an encrypted encryption key, and important information including the variable seq#. The usage rule management program then compares the calculated value with an MAC value stored in the header portion of the flash memory. If these two values are not equal, the usage rule management program disables reproduction of the content thereby preventing the content from being copied in an unauthorized manner.

摘要： An electronic device, information processing device, and adapter device enabling smooth internal circuit switching and other operations are provided. In the electronic device 200, the serial interface 21 and parallel interface 22 are connected via a data bus 23 to the register 24 and data buffer 25, and this data buffer 25 is connected to an ECC circuit 26. The register 24, data buffer 25 and ECC circuit 26 are connected to the memory 28 via a memory interface and sequencer circuit 27. The register 24 is connected to the controller 29, and data input and output is controlled. The interfaces 21 and 22 are switched by means of control signals from this controller 29. That is, switching between these interfaces 21 and 22 is performed through discrimination, by the controller 29, of a portion of the data written to the register 24.

摘要： A security unit to prevent unauthorized retrieval of data includes an encrypting unit for encrypting data in accordance with commands received by the security unit, and a common register for storing both intermediate results and final results of the data encryption. A switching element operatively coupled to the register selectively outputs the contents of the register. The switching element is controlled to prevent external access to the intermediate results of the encryption. The security unit is particularly useful as part of a memory unit that is attachable to a recording/reproduction device such as a digital audio recorder/player.
