    摘要: A method of authorising conditional access to an encrypted digital data product, includes storing at least one set of entitlements in a secure device, each entitlement including a product identifier and expiry information, receiving entitlement control messages from a decoder system including a device for decrypting encrypted digital data products using control words, each entitlement control message including a product identifier, and in a first mode, returning at least one control word in response to an entitlement control message including a product identifier if the product identifier corresponds to a product identifier in a stored entitlement including expiry information indicating the entitlement to be valid, and, in a second mode, progressively adjusting a counter to a pre-determined value and returning at least one control word in response also to entitlement control messages including a product identifier if the product identifier corresponds to a product identifier in a stored entitlement including expiry information indicating expiry of the entitlement and if the counter is at a value between an initial value and the pre-determined value. The counter is set to an initial value to commence operation in the second mode upon receiving an entitlement control message including a product identifier corresponding to a product identifier in a stored entitlement that includes expiry information indicating expiry of the entitlement.

    摘要: A method of partially scrambling a data stream (6) including transport stream packets (7), each transport stream packet (7) having a header (8) and a payload (9), wherein a sequence of transport stream packets (7) has payloads carrying encoded data elements, arranged in units (15), includes: selecting transport stream packets (7) forming a subsequence of the sequence, and scrambling at least part of the payloads (9) of each transport stream packet (7) in the subsequence. The method further includes monitoring the payloads (9) of at least some of the transport stream packets (7) in the sequence for the presence of data (22) indicating a boundary between two subsequent units (15), and, for selected units (15), including at least one of the transport stream packets (7) carrying data forming part of the selected unit (15) in the sub-sequence.

    摘要: Methods and systems related to producing chips with the uniqueness property are disclosed. A random bit vector is generated using a hardware random number generator on the chip or “on the fly” as a hardware component is being produced. The generated random bit vector is stored in a one-time programmable memory of the chip. A value is derived in the chip from the random bit vector programmed in the one-time programmable memory of the chip. The derived value is exported to an external receiving module communicably connected to the chip to enable a security application provider to encrypt a message that is decryptable by the chip using a key based on the random bit vector programmed in the one-time programmable memory of the chip.
