  • Patent number: 8234718
    Abstract: Provided is a method of preventing digital content from being used despite the presence of copy control information. In the method, a security apparatus capable of restricting use of contents generates a nonce with respect to a storage device and stores the nonce in the storage device and a memory separated from the storage device when content is stored in the storage device; updates the nonces stored in the memory and storage device when movement of the content occurs; and permits use of the content only when the nonce of the storage device, which is stored in the memory, is equal to the nonce stored in the storage device if the content is requested for use, thereby preventing a disk cloning attack.

  • Publication number: 20090052670
    Abstract: Disclosed are a method and apparatus for storing digital content in a storage device. A content key, which is a key used by a host for encrypting content when the content is stored to a storage device connected to the host, is encrypted by using a storage key of the storage device. The encrypted content key and encrypted content are stored in the storage device, and the host only stores storage keys. Thus, quantity of information maintained by the host can be reduced. Also, when a storage key is stored in a portable security component (PSC), portability and mobility of content bound to a single host may be improved.

  • Publication number: 20080247540
    Abstract: A method and apparatus for protecting digital content stored in a universal serial bus (USB) mass storage (UMS) device from unlimited distribution are provided. According to the method and apparatus, a UMS device generates a random key according to a request from a user and shows the generated random key to the user, and then, by using the random key, registration data is encrypted. Accordingly, only a USB host that registers the UMS device after the user connects the USB host directly to the UMS device, can freely use digital content of the UMS device, and even if encrypted registration data of the UMS is leaked out, unauthorized devices cannot register the UMS device.
