Abstract: Provided are an electronic device and a method of controlling same. The method of controlling the electronic device: displays a UI including a security index showing that the electronic device is in a state operating in a secure mode; compares the security index to a reference security index and determines whether the security index has been falsified; and when the security index is a falsified security index, shows that the security index is a security index that has been falsified.

Abstract: A method of processing digital content performed by an apparatus for storing digital content. In the method, a hardware regional code extracted from a memory of a content storage device is compared with a firmware regional code extracted from firmware, and the digital content is selectively encrypted and stored according to a corresponding regional code only when the hardware regional code matches the firmware regional code.

Abstract: Provided are a transport stream structure of image data, a transmitting and receiving apparatus and method thereof. A transport stream structure of image data includes a header compressed by a lossless compression algorithm; an additional information field for additional information of image data, the additional information field being generated based on compressing the header by using the lossless compression algorithm; and a payload including the image data. The transport stream structure of the image data, the transmitting and receiving apparatus and method thereof enables inserting the additional information without changing the size of the related art transport stream structure of the image data.

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.

Abstract: A method of managing and restoring an identifier of a storage device and an apparatus therefor are provided. The method includes the operations of generating a storage device identifier; recording the storage device identifier in a non-volatile memory of a host; generating an identifier file including the storage device identifier and a host identifier; and recording the identifier file in the storage device. By doing so, the method and apparatus can efficiently and securely manage the storage device.

Abstract: A method and apparatus for limiting an operation of a digital rights management (DRM) module includes checking an operation mode that is currently set in the DRM module, deciding a DRM policy that will be applied to the DRM module, and selectively limiting an operation of the DRM module based on the checked operation mode and the decided DRM policy.

Abstract: Provided is a method of restricting use of contents in a virtual system comprising at least one virtual machine implemented by applying virtualization technology to a predetermined device. The method includes: reading a first device identifier from the device in order to identify the device; reading a second device identifier, which is a device identifier allocated to the at least one virtual machine, from the at least one virtual machine; determining whether the first device identifier is identical to the second device identifier; and selectively restricting use of contents in the at least one virtual machine based on a result of the determining.

Abstract: Provided are a method of issuing a DRM (digital rights management) key by using a CE (consumer electronics) device management server. The method includes: authenticating the CE device; if authentication of the CE device succeeds, transmitting a request for issuing the DRM key to a key server for storing and managing the DRM key; receiving the DRM key from the key server; and transmitting the DRM key to the CE device. Thus, the CE device can conveniently and safely receive the DRM key.

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.

Abstract: A method and apparatus for managing a client revocation list are provided. The method includes receiving a first client revocation list from a server; and selectively discontinuing an operation of a client, based on the first client revocation list. By doing so, the method and the apparatus can securely control contents.

Abstract: Provided is a method of preventing digital content stored in a universal serial bus (USB) mass storage (UMS) device from being distributed without restriction. In the method, registration data is encrypted in order to allow a UMS device to decrypt and use digital content using time information only within a predetermined term of validity. Accordingly, even if encrypted registration data of a UMS device is disclosed, it is possible to make it difficult for unauthorized devices to store the registration data, thereby preventing content of the UMS device from being distributed without restriction.
