摘要： Some embodiments of the invention provide a method for distributing content over a network. The method distributes a single media storage structure to a device (e.g., a computer, portable player, etc.) that connects to the network. The media storage structure includes first and second pieces of encrypted content. Based on whether the device is allowed to access the first piece of content, the second piece of content, or both, the method provides the device with a set of keys for decrypting the pieces of the content that the device is able to access. The provided set of keys might include one or more keys for decrypting only one of the two encrypted pieces of content. Alternatively, it might include one or more keys for decrypting both encrypted pieces of content. For instance, the selected set of keys might include a first key for decrypting the first encrypted piece and a second key for decrypting the second encrypted piece. Based on the provided set of keys, the device can then decrypt and access either one of the two pieces of content in the media storage structure or both pieces of encrypted content in the media storage structure.

摘要： Disclosed herein are systems, methods, and media for preventing the unauthorized playback of content. A system receives, from a client device associated with a user profile, a download authorization start request for an asset for which the user profile is authorized. That system identifies a number of available slots for progressively downloading content. If the number of available slots is greater than zero, the system assigns an available slot from the number of available slots to the client device to yield an assigned slot. That system transmits security information, a download authorization key, and a download authorization duration associated with the assigned slot to the client device in response to the download authorization start request, wherein the security information and download authorization key allow the client device to start a progressive download of the asset for the download authorization duration. At the end of the download authorization, that system terminates the download authorization and releases the assigned slot.

摘要： A server receives, from a client device associated with a user profile, a download authorization start request 606 for an asset for which the user profile is authorized. The asset can be media content, video, audio, games, images or applications. The server identifies a number of available slots for progressively downloading content and assigns an available slot from to the client device. The slots can relate to authorisation for a limited number of client devices to be associated with the user profile, a session, a lease, a resource, a node, a transmission medium etc. The server transmits a download authorization key, such as a decryption key, and a download authorization duration associated with the assigned slot to the client device 608. Wherein download authorization key allows the client device to start a progressive download (streaming) of the asset for the download authorization duration. At the end of the download authorization duration the client device may transmit a renewal request 610 to the server or the server will terminate the download authorization and release the assigned slot. At any time the client device can send a stop request 614 to terminate the download authorization and releases the assigned slot.

摘要： Method and apparatus for increasing security of a cryptographic algorithm such as deciphering, enciphering, or a digital signature using a block type cipher such as AES implemented for instance in a "whitebox" model with the cipher key either known or unknown at the compilation time. This method is secure for use in entrusted environments, particularly for securing cryptographic keys. The look up tables characteristic of such algorithms are protected against attack here by making all such tables of the same size and indistinguishable, and further by masking the output values of such tables, typically where the tables carry out a permutation function or a logical exclusive OR operation.

摘要： For digital rights management (DRM) of e.g. digitally delivered music or video, a technique to make the decryption keys more secure. The technique fragments a message (song or video or other) into a number of portions, and uses a different decryption key for each portion. Each of the various keys is a function of the preceding key, in one version. In another version, each key is a function of a seed value and of the particular portion of the material with which the key is associated.
