    摘要： A method and apparatus for acquiring and removing information regarding a digital rights object are provided. The method for acquiring removing information regarding a digital rights object includes receiving a request for data on a rights object from a device, processing the data on the rights object in response to the request, and providing the processed data to the device. The method of removing a digital rights object includes selecting information regarding a rights object to be removed, encrypting the selected information regarding the rights object using a common encryption key, embedding the encrypted information regarding the rights object into a signal to be transmitted to a portable storage device, and transmitting the signal to the portable storage device. A device requests information regarding a rights object from a portable storage device, receives the information regarding the rights object from the portable storage device, and removes an unnecessary rights object.

    摘要： A system and method for transmitting/receiving encryption information in a mobile broadcast system supporting broadcast service (BCAST) are provided. In the mobile broadcast system, a BCAST Subscription Management (BSM) manages subscriber information of a terminal, and transmits to a BCAST Service Distribution/Adaptation (BSD/A) a first delivery message including a Registration Key Material (RKM) provided for registration of the broadcast service of the terminal and including at least one service or content's identifier. The BSD/A transmits to the BSM a first delivery confirmation message including information indicating success/fail in receipt of the first delivery message, and transmits the RKM to the terminal.

    摘要： Disclosed are a method and a system for mutual inclusive authentication between a service provider, a terminal and a user identity module. The authentication system is configured in a structure that can interact with a public key infrastructure of the current network security environment and can be independently used in a specific network system. The inclusive authentication method is divided into public key authentication and symmetric key authentication. Mutual authentication can be made between a service provider, a terminal and a user identity module using any of the two authentication schemes. Then a user can access content on any terminal device using the content license based on the user's identity.
