An authentication method of a storage device includes requesting an EID (Encoded IDentifer) to the storage device by an authentication device for authenticating the storage device, receiving the EID by the authentication device, restoring original ID information by decoding the received EID, and verifying individual ID information corresponding to use of the storage device included in ID information by using ID authentication information received from the storage device, wherein the ID information includes multiple pieces of individual ID information corresponding to the use of the storage device.
摘要:
A mobile broadcast system for delivering a notification event for generation of a notification message for information provisioning to a subscriber receiving a broadcast service is provided. The mobile broadcast system includes a first apparatus for managing subscriber information of the broadcast service, handling generation of at least one notification message according to at least one notification event, and generating a response message indicating generation end of the notification message; and a second apparatus for sending a notification event message for requesting generation of the notification message to the first apparatus according to the at least one notification event, receiving the response message in response thereto, and then handling delivery of the notification message over a broadcast channel or an interaction channel.
摘要:
Disclosed is an inter-entity coupling method for service protection in a broadcast environment including a terminal and a broadcast network, which includes a Broadcast Service Application (BSA), a Broadcast Service Distribution (BSD) and a Broadcast Service Management (BSM) function. The method includes executing enrollment and service joining procedures for the terminal, wherein the terminal acquires a group key in the enrollment procedure and acquires a Rights Object (RO) for the service in the service joining procedure; receiving a message including a traffic key in the terminal; acquiring the traffic key from the message using the RO; receiving an encrypted service encrypted by the BSD in the terminal; and decrypting the encrypted service using the traffic key in the terminal.
摘要:
A method and apparatus for using a non-volatile storage device includes reading device identification information from the non-volatile storage device, application identification information corresponding to a content application related to a type of content to be protected or utilized among a plurality of content applications is acquired, usage identification information is generated using the device identification information and the application identification information, and protecting or utilizing content using the usage identification information.
摘要:
Methods and apparatus are provided for providing a DRM service by a user terminal apparatus consuming DRM content in a service environment that provides the DRM content using a plurality of incompatible DRM systems. A license corresponding to the DRM content is acquired from a service providing apparatus that provides the DRM content. It is determined whether the license is a common license having a common DRM interface format. The common DRM interface format of the common license is converted to a format of a first DRM system installed in the user terminal apparatus, when the license is the common license. The license having the format of the first DRM system is applied in reproducing the DRM content. The common license is provided from the service providing apparatus to the user terminal apparatus through a common DRM interface when the service providing apparatus does not support the first DRM system.
摘要:
A method and apparatus are provided for providing a DRM service in a user terminal apparatus providing an adaptive streaming service. Content protection information is received that includes information about multiple DRM systems applied to specific content provided using the adaptive streaming service. A specific DRM system is selected from among the multiple DRM systems. A license corresponding to the specific DRM system is acquired. The license includes an encryption key capable of decrypting the specific content. The specific content is decrypted using the acquired license.
摘要:
An encryption key distribution method for service and content protection in a mobile broadcasting system, and a system for the same which includes generating, by a network, a first encryption key when the broadcast service is first provided; transmitting a generalized rights object message, which includes identification information for identifying the generated first encryption key, to the terminal; generating a second encryption key before the lifetime of the first encryption key expires; and transmitting the generalized rights object message, which includes identification information for identifying the generated second encryption key, to the terminal.
摘要:
A method and apparatus for managing digital rights of a portable storage device are provided. The method comprises a device performing authentication together with the portable storage device and sharing an encryption key with the portable storage device as a result of the authentication, requesting a rights object list from the portable storage device, receiving the rights object list from the portable storage device, and processing and displaying the rights object list.
摘要:
A method of playing back content based on digital rights management (DRM) between a portable storage and a device and a portable storage for the same are provided. The method includes requesting the portable storage to set a playback right for content protected through DRM, receiving an encrypted playback right for the content protected through DRM from the portable storage, and decrypting the encrypted playback right and playing back the content protected through DRM using the decrypted playback right.
