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.

Apparatus and method for content encryption and decryption based on storage device ID

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.

Apparatus for generating secure key using device and user authentication information

A method for operating a memory system includes providing a memory system including a memory controller, and first and second memory devices constituting a ring topology. The memory controller is connected to the first memory device through first and second links. The second memory device is disposed on the first link. The first memory device starts a first operation. The first link is used as a communication path between the first memory device and the memory controller. The second memory device starts a second operation before the first memory device completes the first operation. The communication path between the first memory device and the memory controller is changed into the second link. The first link is used as a communication path between the second memory device and the memory controller.
