System and method for managing encrypted content using logical partition
2.
The present invention support that process of proces the title key and its background, which is delayed when the binding information changes. The invention supports the correct counting of the devices needed to restore the rebinding process when the devices fail or go offline unexpectedly during processing. The invention uses the binding background to represent a set of data, which can be used to determine whether the binding information used to encrypt a set of title keys is outdated or not, and allows rebinding to the current cluster binding information level.
3.
The content binding service preferably has the ability to determine the "cycle" of binding information according to the information contained in the binding background, and can use the information in the background to refer to the actual binding information that needs to be decrypted by the encrypted title key. When it is necessary to obtain encrypted content, the content provider preferably identifies the logical partition, and the encrypted title key of the requested content is a number.
