摘要： A technique for securely transferring content from a first device in a first layer to a second device in a second layer. In one embodiment, the first device is a device in a trusted domain and the second device is outside of the trusted domain. Transfer of protected content to another device may require authentication of the receiving device. A rights file which specifies the rights of the receiving device to use the protected content, according to its security level is also transferred. These rights may concern, e.g., the number of times the receiving device may transfer the protected content to other devices, the time period within which the receiving device may play the protected content, etc. The higher the security level of the receiving device, the more rights accorded thereto. A minimum security level requirement may be imposed in order for protected content to be transferred to a device.

摘要： To provide a playback device capable of requesting for a content generated in a format compatible with its processing capability and playing back the content, with no need of user input of a user ID or the like. A playback device for playing back contents reads, from an external recording medium, a playback right of a content to play back one or more contents that each have been generated based on a content and in a format compatible with a processing capability different for each playback device, and transmits the playback right and capability information indicating a processing capability of the playback device to a server device. The playback device acquires, from the server device, one of the one or more contents corresponding to the playback right in a format compatible with its processing capability indicated by the capability information, and plays back the acquired content.

摘要： A method for order relationship authentication, including: a visited mobile multimedia broadcasting-conditional access system (MMB-CAS) acquiring operation and management information from a corresponding business operating support system (BOSS); the visited MMB-CAS receiving a request message for accessing service key from a user and triggering order relationship authentication; the visited MMB-CAS requesting the home MMB-CAS to perform order relationship authentication on the user; and the visited MMB-CAS receiving an order relationship authentication result of the user fed back from the home MMB-CAS, and performing corresponding processing. The present invention also provides an order relationship authentication system and a Mobile Multimedia Broadcasting-Conditional Access System. By the present invention, the amount of data synchronized between MMB-CASs is reduced and the overall performance and reliability of the system is improved.

摘要： A Digital Rights Management (DRM) system provides a lightweight layering of encryption and decryption of keys that allows efficient use of different cryptographic techniques to effect the secure delivery of multimedia content. Asymmetric cryptography, where a public key is used to encrypt information that can only be decrypted by a matched private key, is used by the DRM system to deliver symmetric keys securely.

摘要： At a seller, an encryption device encrypts content data stored in a content server using an encryption key generated by an encryption key generation device, and records the encrypted content data and a communication program on a recording medium. A paper indicating an identification code unique to each recording medium is attached to the recording medium. A decryption key corresponding to the encryption key and the identification code are registered in a managing database. A user terminal sends the identification code to a decryption key managing server apparatus via Internet in accordance with the communication program, in a case where the user terminal is to copy or install or reproduce the content data stored on the recording medium. The decryption key managing server apparatus sends a decryption key corresponding to this identification code to the user terminal. The user terminal decrypts the content data using the decryption key sent thereto.
