Zusammenfassung:The present invention provides a means for managing title keys by establishing logical partitions of title keys encrypted with the same binding information. The invention supports delayed and background processing of title keys when binding information changes. This invention supports proper accounting for devices required to recover rebinding processing when devices fail or go offline unexpectedly during processing. The invention uses binding context which represents a set of data that can be used to determine if the binding information used to encrypt a set of title keys is outdated and allow for rebinding to the current cluster binding information level.
