    Abstract: An apparatus and method for encrypting content based on an identifier (ID) of a storage device and a decrypting apparatus and method corresponding thereto. The content recording device includes a storage device interface to receive a first primitive ID and a second primitive ID to identify first and second portions provided in a storage device from the storage device, and a processor to generate a media ID that is a unique ID of the storage device using the first primitive ID and the second primitive ID and to encrypt one or more contents using an encryption key generated using the media ID, wherein the storage device interface provides the content encrypted by the processor to the storage device.

    Abstract: A secure key generating apparatus comprising an ID calculating unit receiving a primitive ID from a first storage device and calculating a first media ID, (a unique identifier of the first storage device), from the first primitive ID; a user authentication information providing unit providing user authentication information for authenticating the current; and a secure key generating unit for generating a first Secure Key using both the first media ID and the first user's authentication information. The Secure Key is used to encrypt/decrypt content stored in the first storage device. The secure key generating unit generates a first different Secure Key using a second media ID of a second storage device, and generates a second different Secure Key using second user's user authentication information. Only the first Secure Key can be used to decrypt encrypted content stored in the first storage device that was encrypted using the first Secure Key.

    Abstract: A memory system includes a storage device and a host device. The storage device includes a memory device and a device controller. The device controller is configured to store device information. The device information includes a level of a power supply voltage required for the memory device. The host device includes a host controller and a power management integrated circuit (PMIC). The host device is configured to send a query command to receive the device information from the device controller during a power setting period. The PMIC is configured to supply a first level of power supply voltage to the memory device during the power setting period and, after the power setting period, selectively supply one of the first level of power supply voltage and a second level of power supply voltage to the memory device. The first level of power supply voltage is lower than the second level of power supply voltage.
