    摘要： Systems and method are disclosed for performing profiling on a secure device. In embodiments, a plurality of counters are established. Each counter may be related to a different type of message. When the secure device receives and/or processes a message, it determines the type of message and adjusts a counter related to the determined message type. A ratio may be computed between the different counters. When the ratio deviates from a threshold, the secure device may be performing illegitimate operations, and one or more countermeasures are deployed against the illegitimate secure device.

    摘要： Systems and methods for implementing a Transport I/O system are described. Network encrypted content may be received by a device. The device may provide the network encrypted content to a secure processor, such as, for example, a smart card. The secure processor obtains a network control work that may be used to decrypt the network encrypted content. The secure processor may decrypt the network encrypted content to produce clear content. In embodiments, the secure processor may then use a local control word to generate locally encrypted content specific to the device. The device may then receive the locally encrypted content from the secure processor and proceed to decrypt the locally encrypted content using a shared local encryption key. The transport I/O system ensures the protection of the network control word by maintaining the network control word on the secure processor.

    摘要： A method and a system relates to a cellular-network assisted Pay-Per-View (PPV). An issue arises in reconciling PPV purchase balance data when a Set-top Box (STB) lacks a communication link to the PPV headend server. The present disclosure addresses the issue by using a mobile computing device for delivering the PPV balance data from the STB to the PPV headend server over a cellular-network. The mobile computing device receives the PPV balance data from the Conditional Access Module (CAM) on STB through near-field communications. The mobile computing device, when it is moved to inside a service coverage area of a cellular or Wi-Fi-network, transmits the PPV balance data to the PPV headend server. The PPV headend server updates the PPV balance data and transmits the updated PPV balance data to the CAM on STB via the satellite broadcasting network.

    摘要： The various examples described herein generally provide systems and methods for generating a hybrid electronic programming guide (EPG) that includes both broadcast content and other types of content, such as over-the-top (OTT) content. In examples, broadcast content may be content provided by a satellite, terrestrial, or cable television provider. Other types of content, e.g., the OTT content, may be content that is delivered over an open network, such as the Internet. In examples, a secure processor may be employed to determine if a subscriber is authorized to access the OTT content based on subscription information received via a broadcast transmission.
