Abstract: A system and method for storing and retrieving program material for subsequent replay is disclosed. The method comprises the steps of receiving access control information and the program material encrypted according to a first encryption key, the access control information including the first encryption key and control data; further encrypting the access control information and the encrypted program material according to a second encryption key; encrypting the second encryption key according to a third encryption key to produce a fourth encryption key; and storing the encrypted access control information and encrypted program material and the fourth encryption key.

Abstract: One or more embodiments of the invention provide a method, apparatus, and article of manufacture for providing access to digital services. Configuration information that has been transmitted asynchronously is received in a security component (that is configured to control access to the digital services). A hardware state machine (that comprises custom logic that is used to control access to the digital services) in the security component is then dynamically reconfigured based on the configuration information.

Abstract: One or more embodiments of the invention provide a method, apparatus, and article of manufacture for limiting unauthorized access to digital services. A hidden non-modifiable identification number is embedded into a nonvolatile memory component. The nonvolatile memory component is used to contain state information to provide desired functionality and enforce one or more security policies for accessing the digital services. Also, the hidden number uniquely identifies a device containing the nonvolatile memory component and access to the digital services is based on access rights associated with the hidden number. Once embedded, access to the nonvolatile memory component is isolated such that access to the identification number is limited to a fixed state custom logic block, the nonvolatile memory component is protected from modification such that it is read only, and the nonvolatile memory component is not directly accessible via a system bus.

Abstract: A system and method for storing and retrieving program material for subsequent replay is disclosed. The method includes accepting a receiver ID associated with a receiver key stored in a memory of the receiver, determining a pairing key for encrypting communications between the conditional access module and the receiver, encrypting the pairing key with the receiver key, and transmitting a message comprising the encrypted pairing key to the receiver. The apparatus comprises a receiver for receiving a data stream transmitting a media program encrypted according to a media encryption key and an encrypted media encryption key and a conditional access module, communicatively coupleable with the receiver.
