Summary:Space-efficient methods of defining a key allocation scheme within a broadcast encryption system are provided. In some embodiments, a descriptor is received. The descriptor includes a plurality of subset definitions and a plurality of pointers. A data segment is resolved from each of the plurality of pointers. The resulting data segments are assembled into a plurality of variant definitions. A media key block is generated from the plurality of subset definitions and the plurality of variant definitions.
