<p>A method of providing access to encrypted content to one of a plurality of consumer systems (2-6),
each consumer system being able to obtain a secure content package, including the encrypted content and an indication of a location from which to request a rights data object, the rights data object including at least content key information enabling decryption of at least part of the encrypted content and being cryptographically bound to at least the device to which it is issued, such that only devices (2-4,6) with an agent function to which the rights data object has been bound are able to obtain the content key information, is characterised by transferring a rights issuer module to a protected environment (25) of a device (24) for incorporation in the one consumer system, enabling the device, when operational in the consumer system, to generate at least one rights data object cryptographically bound to a requesting one of the devices in the consumer system provided with an agent function.</p> |
